curious question. suppose you have 300 different strings and they need all be replaced to say "aaa".
is it faster to replace each one sequentially (i.e. replace first string to aaa, then do the 2nd, 3rd,...) , or is it faster to use a regex with “or” them all and do replace one shot? (i.e. "1ststr|2ndstr|3rdstr|..." -> aaa) let's say the sourceString this replacement to be done on is 500k chars. Anyone? i suppose the answer will be similar for perl, python, ruby. btw, the origin of this question is about writing a emacs lisp function that replace ~250 html named entities to unicode char.
