You don't have to use /[#]/x, you can use /\#/x just as well; just like you more or less have to use /\ /x in order to be able to match a space.

    /[ ]/x matches a space as well.
      But the regular expression engine is more likely to be able to optimize a literal character as opposed to a character class.
        That's true. Pity noone has written an optimizer-optimizer which translates one character character classes to literal characters.
