in thread Why? (each...)

Curly braces create an anonymous hash and return a reference to it.
Square brackets create an anonymous array and return a reference to it.
Parenthesis, in the context of this discussion, indicate a list.

Anonymous in the sense that there is no named variable for the hash or array -- you have to access them via the reference.

    What does "indicates a list" mean? 

    my %h = ($x);  # List created for RHS.
my %h = $x;    # List created for RHS.
my $s = ($x);  # No list created for RHS.
my $s = $x;    # No list created for RHS.
