+Challenge 1: "Write a script to output the same number of PI digits
+as the size of your script. Say, if your script size is 10, it should
+print 3.141592653."
+
+Note that it DOESN'T SAY "calculate the same number of PI digits..." so
+I took the liberty to grab them over the internet (via a bitly link I set
+up to shorten the URL and hence the program) rather than generate them
+on the fly, because generating Pi is so dull.
+
+Note that ch-1.pl takes an optional single command line argument to tell
+how many digits to print, if absent the default is to use the size of
+the script as the question wanted.  I built two cut down versions of the
+script, but didn't include them here.
+
+
+Challenge 2: "You are given a file containing a list of words (case
+insensitive 1 word per line) and a list of letters. Print each word from
+the file than can be made using only letters from the list. You can use
+each letter only once (though there can be duplicates and you can use
+each of them once), you don't have to use all the letters."
+
+This is a natural "bag of words" question, essentially we need to build
+a "bag subset" operation.  See ch-2.pl for the solution, simple and obvious
+(I love Perl's hashes especially for their idiomatic set and bag uses).

+
+I'm new to Perl 6 so looking for interesting (not necessarily optimal
+solutions) to try out some of the cool features that Perl 6 gives over
+Perl 5 - especially as it is basically a new language with new syntactic
+sugar....
+
+# Problem 1
+
+This is quirky same code between Perl 5 and Perl 6 produce different output - Perl 6 displays one more digit of Pi... so we need to extend the script by one byte (adding ";") to the end of the line...
+
+```
+perl -Mfeature=say perl5/ch-1.pl
+perl6              perl6/ch-1.p6
+```
+
+# Problem 2
+
+## Perl 5
+
+This is a nice problem - I solved this in Perl 5 in two ways - firstly with nested loops - but this requires a label (which is ugly code) to break out of the inner loop and get to the next word. The neater solution requires encapsulating the inner loop inside a function and calling that. Returning true if the word can be matched and false otherwise.
+
+The first part collects together the counts of the letters and the second loops through each of the words to see if there are sufficient letters.
+
+The loop is destructive of the counts array so we pass a copy into the function rather than the usual pass by reference.. This effectively clones the counts array so we don't have to do this explicitly
+
+For 2a see notes about perl 6 (this is non-destructive...)
+```
+perl perl5/ch-2.pl back < /usr/share/dict/british-english-insane
+perl perl5/ch-2a.pl back < /usr/share/dict/british-english-insane
+```
+
+## Perl 6
+
+Because Perl 6 can't pass by value - I've rewritten this to be non-destructive (the checkword function counts up and compares to the main count)... need to check for performance....
+
+The other change is split - you don't use the empty regex "//" to perform the split - rather the empty string (something frowned upon in Perl5) and to remove the rogue white-space split adds you need to include the additional flag `:skip-empty`
+
+I haven't golfed this one entirely - but have used "golf" techniques along the way to make the code in someways more readable using grep rather than if for instance!
+```
+perl6 perl6/ch-2.p6 back < /usr/share/dict/british-english-insane
+```
+
+## Timings
+
+Yet again perl5 out performs perl 6 - perhaps I need to know how to optimize perl 6 code...
+
+```
+  perl5    ch-2.pl        1.9 seconds
+  perl5    ch-2a.pl       1.3 seconds
+  perl6    ch-2.p6       27.1 seconds
+```
+
+This time by what looks like a factor of 20.... need a Perl 6 expert to suggest why....
