NAME

invoker - implicit invoker, sort of

SYNOPSIS

  use invoker;

  sub foo {
    my $self = shift;
    $->bar; # calls $self->bar;
  }

  # use Method::Signatures::Simple
  # method {
  #  $->bar # ditto
  # }

DESCRIPTION

the invoker pragma enables the $-> syntax for invoking methods on $self , inspired by Perl6's $.method invocation.

The module does not inject the $self variable for you. you are encouraged to use it in conjunction with self, selfvars, <Method::Signatures::Simple>, or other similar modules.

The following syntax works:

$->foo( .. args ...)

$->foo

$->$method_name

$->$method_name( .. args ...)
