in thread validation of posted data.

I've found 
if ($display =~ /[^\-a-z0-9\.]/) {
  #err
}

[download]
to be easiere to read most of the time.
Also if you _read_ the code, Yours says: unless $display is all good chars make an error. Where this says: If there are any illegal chars make an error. I find the latter easiere to understand.

Now appearing as itself... "."!

    Kind of a tangent, here, but isn't "." acceptable by itself (i.e., unescaped) in a character class, since its function as a metacharacter there wouldn't make much sense?

      Yes I believe it is, but I find it easiere to see that a literal period is required when it is escaped instead of examining the context and determening it from there.
