Re: Search string for occurneces of words stored in array

sentence =~ Regexp.union(*words)
one addition regarding the regexp, though. in case words may
contain special characters, it's safer to escape them first:

sentence =~ Regexp.union(*words.map { |word| Regexp.escape(word) })
It actually does it for you:

Regexp.union("a",".b") => /a|\.b/
ha, didn't know that ;-) thank you!
