In Independent routines§

See primary documentation in context for sub pop

multi pop(@a) is raw

Calls method pop on the Positional argument. That method is supposed to remove and return the last element, or return a Failure wrapping an X::Cannot::Empty if the collection is empty.

See the documentation of the Array method for an example.

In Array§

See primary documentation in context for method pop

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␤»

In role Buf§

See primary documentation in context for method pop

method pop()

Returns and removes the last element of the buffer.

my $bú = Buf.new( 1, 1, 2, 3, 5 );
say $bú.pop(); # OUTPUT: «5␤» 
say $bú.raku;  # OUTPUT: «Buf.new(1,1,2,3)␤»
