Yes, I do that for expressions that are not in a loop that runs a
zillion times, this because in Perl up to 5.8.8 the "[.]" is a bit less
fast than "\.".
In Perl 5.10 this difference is gone: "[.]" and "\." lead to the same
opcodes.
Another thing is that [.] survives interpolation: ("[.]" eq '[.]', "\."
eq '.').
I started using "[.]" and "[?]" and "[*]" etc., in procmail recipes.
