I'm inclined to suggest the regex compiler should issue a warning for 
this.

I've never seen a character range other than A-Z, a-z, or 0-9.  Well, I 
suppose A-F or a-f if you're trying to match hex digits (and some 
variations on that for octal).  But, I can't imagine any example where 
somebody wrote A-z and it wasn't an error.
