Re^7: Checking input

Hmm.. I wonder where I picked that up then. Or was I conflating it with dot? Could be.

My whole point was that something like `[a-]` looks like it is a typo on the programmer's part. If I saw this in a script my first question would be "Did you mean something like `[a-z]`?" If I saw `[-a]` it doesn't look like a typo. Nor does `[a\-]` look like a typo. I can't really explain it any more clearly than this. And I should note that this is a lot more trouble than I thought it would be. ;) Such a simple question shouldn't ever have to go to a Re^7...	[reply] [d/l] [select]
