* Throws any throwable 'sneakily' - you don't need to catch it, nor declare that you throw it onwards.
* The exception is still thrown - javac will just stop whining about it.
*
* Example usage:
*
* <pre>public void run() {
* throw sneakyThrow(new IOException("You don't need to catch me!"));
* }</pre>
*
* NB: The exception is not wrapped, ignored, swallowed, or redefined. The JVM actually does not know or care
* about the concept of a 'checked exception'. All this method does is hide the act of throwing a checked exception
* from the java compiler.
*
* @param t The throwable to throw without requiring you to catch its type.
* @return A dummy RuntimeException; this method never returns normally, it <em>always</em> throws an exception!
