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'"
