This package modifies the consuming package and provides a mechanism for assembling complex pattern matching operations.

The match method returns a Venus::Match object having the match value set to the invocant or the result of a dispatch. This method supports dispatching, i.e. providing a method name and arguments whose return value will be acted on by this method.

match(string | coderef $method, any @args) (Venus::Match)

{ since => '0.04', }

=example-1 match

package main;

my $example = Example->new;

my $match = $example->match;

# bless({..., value => bless(..., 'Example')}, 'Venus::Match')
