# ABSTRACT: Smartmatch done right

=head1 NAME
Syntax::Infix::Smartmatch - Smartmatch done right
=head1 VERSION
version 0.011
=head1 SYNOPSIS
say "YES" if $value ~~ [1, 2, qr/42/];
=head1 DESCRIPTION
B<NOTE: This module is currently still experimental and the details of its behavior may still change>.
This module implements a new, much simplified version of smartmatch. In particular the behavior only depends on the right side argument. In particular it will do the following based on the right side argument:
=over 4
=item * undef
This will return C<not defined $left>.
=item * object
If the object has smartmatch overloading (note: this might disappear in a future Perl version), that is called. Otherwise it returns object identity.
=item * regex
This is equivalent to C<$left =~ $right>.
=item * sub
It will return the value of C<< $right->($left) >>
=item * array
This will return true if C<$left> smartmatches any of the members of C<@$right>.
=item * other
This will return C<$left equ $right> (C<defined $left and $left eq $right>).
