Perhaps I'm missing something, but how does this differ from what you would expect based on the behavior documented in perldata (at "Context," the second major heading) or, more or less comprehensively, in virtually any introductory-level text (say, "Learning Perl", for example)?

See also ?node_id=3989;BIT=list%20scalar%20context.

Update: Duh; forgot to paste...

#!/usr/bin/perl
use strict;
use warnings;
use 5.012;

my @foo = qw(one two three);
say @foo;
my $val = @foo;
say $val;

=head output:
