Yes, that was stupid of me. Thank you for pointing out my error.

Part of it is that I always use m{ ... } rather than / ... / so I have lost the habit of escaping slashes. The other part is I didn't realise that there was interpolation inside a character class so, as you point out, I failed to escape the $. Ought to do the @ as well, I suppose. Not sure about the &?

$ perl -le '
> use strict; use warnings;
> print q{whatever} =~ m{[\$&<>\@/]} ? q{Yep} : q{Nope};'
Nope
$ perl -le '
> use strict; use warnings;
> print q{v$table} =~ m{[\$&<>\@/]} ? q{Yep} : q{Nope};'
Yep
$ perl -le '
> use strict; use warnings;
> print q{bill@bloggs.com} =~ m{[\$&<>\@/]} ? q{Yep} : q{Nope};'
Yep
