Then $extension is a CV which isn't that much slower in comparison as a
CONST, so from engine-performance-perspective: no big deal -> spend your
time optimizing on other places where it has more effect than the time
you loose on teaching people about all the fancy string functions (where
we already have more than enough)

too many functions hurt more on readability imo ...
