Re^2: Add Perl Varibles in system()

Normally when list context is needed you might say (my $s)=func_returning_list();, with the my on the inside

my ($s) causes list context too.

Note that you would not say my ($x,$y) as that is actually a syntax error.

That works fine here on perl 5.10.0 and on any earlier perl I can remember

$ perl -Mstrict -cwe 'my ($x,$y)'
-e syntax OK

I must be getting old. I distinctly remember learning that lesson when Perl 5 was freshly minted. The grammar must have been "improved" since then. You are right about the latter for sure; how many times do I say `my ($x,$y,$z)= @_; </code? So the <code>my ($x)` [download] vs `(my $x)` must be (or have been) something more subtle.

I verified that it works as far back as 5.6.0, but I'm sure it worked even before that.	[reply]
