Apparently (undef)[0] is being interpreted as a null list. In the context of the other statements, why is that? Thanks...
%tmp= (nothing => undef, one => 1);
# $tmp{nothing} is undef
%tmp= (nothing => (0, undef)[0], one => 1);
# $tmp{nothing} == 0
%tmp= (nothing => [undef, 0]->[0], one => 1);
# $tmp{nothing} is undef
%tmp= (nothing => scalar ((0, undef)[1]), one => 1);
# $tmp{nothing} is undef
%tmp= (nothing => (undef), one => 1);
# $tmp{nothing} is undef
%tmp= (nothing => (undef)[0], one => 1);
# $tmp{nothing} eq 'one'*** Why not undef?
%tmp= (nothing => (undef, 0)[0], one => 1);
# $tmp{nothing} eq 'one'*** Why not undef?
1;
