method pop(Array:D:) is nodal

Removes and returns the last item from the array. Fails if the array is empty.

Like many Array methods, method pop may be called via the corresponding subroutine. For example:

my @foo = <a b>; # a b 
@foo.pop;        # b 
pop @foo;        # a 
pop @foo;
CATCH { default { put .^name, ': ', .Str } };
# OUTPUT: «X::Cannot::Empty: Cannot pop from an empty Array␤»
