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][0-9] to do that?

Elementry, my dear newbie.  Hehe.  Thanks all!
