NAME

invoker - implicit invoker, sort of

SYNOPSIS

  use invoker;

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

  use methods-invoker;
  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 ...)

CAVEATS

Regular hash access must still be written as $self->{attr} instead of $->{attr}.

Internally, the module installs a parser hook to replace $-> ($- and the gt operator) with $--> (an invocation on the $- perlvar. It also injects an entersub hook to replace $- with $self.

BUGS

TODO

custom invoker name with "use invoker '$this'"
