The solution for matching using regexps isn't that simple. It's more
like this:
"Hello world".match /^#{Regexp.escape('hello')}/
because if the substring I'm checking for contains characters that
would be considered special in a regexp, then they must be escaped or
else it'll cause a (possibly silent) error. So I don't like this
solution so much since it essentially amounts to typing:
big_string.match(/^#{Regexp.escape(little_string)}/)
instead of simply:
big_string.start_with?(little_string)
