Sheeesh - thats cool! I don't wanna event think of how much code this would
need in java - _with_ a regexp-package. Not to mention with the builtin
string manipulating "capabilities".

And its actually the first example of the slice-step-argument I've seen -
which doesn't mean much, but I always asked myself what use they had.
