What does 3.2 mean?

It means that Perl parser can understand things such as
my $object = new Module @args
To do that, it need a hint of what the bareword "Module" means.

If
$var =~ s/,+$//gm;
does even work better, then Jame's data is complexer than I was prepared
to assume.
Next episode:
$var =~ s/,+(?=\s*$)//;
(which also removes more than "trailing commas")
And s/,+(?=\s*)$// isn't the same, see perlre:
"two zero-width assertions next to each other work
as though they're ANDed together"
