NAME

Syntax::Infix::Smartmatch - Smartmatch done right

VERSION

version 0.004

SYNOPSIS

say "YES" if $value ~~ [1, 2, qr/42/];

DESCRIPTION

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:

  • undef

    This will return not defined $left.

  • object

    If the object has smartmatch overloading (note: this might disappear in a future Perl version), that is called. Otherwise it returns object identity.

  • regex

    This is equivalent to $left =~ $right.

  • sub

    It will return the value of $right->($left)

  • array

    This will return true if $left smartmatches any of the members of @$right.

  • other

    This will return $left equ $right (defined $left and $left eq $right).
