NAME
Syntax::Infix::Smartmatch - Smartmatch done right
VERSION
version 0.001
SYNOPSIS
say "YES" if $value ~~ [1, 2, /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 compare every element of
@$left
to see if it smartmatches every element of@$right
. E.g.$left->[0] ~~ $right->[0] && $left->[1] ~~ $right->[1] && ...
bool
This will always return
$right
. This particularly is useful in second order constructs such as Syntax::Keyword::Match (e.g.case($topic > 1)
. Bools are only available on perl v5.36 and up.other
This will return
$left equ $right
(defined $left and $left equ $right
).
