I see the opposite, in some ways... 8 ereg_replace() plus test
statements where one stripslashes() would do the trick... (when
you come from perl, and you have to do everything with
regexp's, it seems 'natural' to do lot's of them...)

An idea I've toyed with, for a while: benchmarking and "costing"
each function, so somebody could add up the "cost" of a page.
Disk hits have a cost, regexps have a cost, even lowly
strtoupper has a cost...

How can we guide programmers to the path of least "cost"? What
techniques can we use to determine "cost"?
