Need Help??

in reply to Re^4: $1[ (reserved != allowed)
in thread $1[

By the way, today I've found that in Modern_Perl book, as an example is given @3 as incorrect name:

These are invalid Perl identifiers:
my $invalid name;  # space is invalid
my @3;             # cannot start with number
my %~flags;        # symbols invalid in name
[download]

(from 4th edition, page #13)
