Not everybody
Not everyone knows how to tie his shoelaces.
One who doesn't tie his shoelaces doesn't mean he doesn't know how to do
it. ;)
Regular expressions are no more against the spirit of Pascal
than associative arrays (hash tables) or any other feature
that is added by using a unit.

You've implemented some kind of 'cut'. But grep is also very useful (and
more often used in a shell, at least by me).
