in thread Perl6: What is "idfirst letter"?

Well, in Perl5, "[" and U+0001 are allowed as the first (and only) character of an identifier, but I don't think anyone would consider them idfirst. I don't know if Perl6 has such exceptions.

Replies are listed 'Best First'.

    No. There are special variables with "weird" names ($/, $!, $) but they aren't identifiers.

    I also don't think that [ counts as an identifier character in Perl 5, because you can't write sub [ { }
