That bracketed construction is called a character class.
This may sound like a stupid question, but... within a regular expression, are the
values in brackets evaluated consecutively, or no? For example:
Does [a-zA-Z0-9] (yes, I know [:alnum:] is the same) mean that there can be a number,
but it has to follow a letter? Or would you just do [a-zA-Z]
