+# Challenge 063
+#
+# TASK #1 > Last Word
+# Submitted by: Mohammad S Anwar
+# Reviewed by: Ryan Thompson
+#
+# Define sub last_word($string, $regexp) that returns the last word matching
+# $regexp found in the given string, or undef if the string does not contain a
+# word matching $regexp.
+#
+# For this challenge, a "word" is defined as any character sequence consisting
+# of non-whitespace characters (\S) only. That means punctuation and other
+# symbols are part of the word.
+#
+# The $regexp is a regular expression. Take care that the regexp can only match
+# individual words! See the Examples for one way this can break if you are not
+# careful.
+#
+# Examples
+# last_word('  hello world',                qr/[ea]l/);      # 'hello'
+# last_word("Don't match too much, Chet!",  qr/ch.t/i);      # 'Chet!'
+# last_word("spaces in regexp won't match", qr/in re/);      #  undef
+# last_word( join(' ', 1..1e6),             qr/^(3.*?){3}/); # '399933'
