[IRCServices Coding] AKILL question

[Elijah]

Would it be possible to have akills able to recognise the difference between
letters, numbers, and non-alphanumeric characters?

For instance, to akill the following users:

Dopey!~y968442N at ip68-97-194-40.ok.ok.cox.net
Dopey!~v514490A at ip68-97-194-39.ok.ok.cox.net

You would use an akill using some unused character to represent that the first
character in the ident is a letter, and another to represent each character that
is a letter, and another for non-alphanumeric.

Example: %######%@* would akill any client with first and last characters being
letters, with has six numbers in-between.

It's relatively hard for me to explain this simply, perhaps due to lack of
sleep. But any thoughts, suggestions, or comments would be appreciated.
