NAME

match::simple - simplified clone of smartmatch operator

SYNOPSIS

   use v5.10;
   use match::simple;
   
   if ($this |M| $that)
   {
      say "$this matches $that";
   }

DESCRIPTION

match::simple provides a simple match operator |M| that acts like a sane subset of the (as of Perl 5.18) deprecated smart match operator. Unlike smart match, the behaviour of the match is determined entirely by the operand on the right hand side.

• If the right hand side is undef, then there is only a match if the left hand side is also undef.

• If the right hand side is a non-reference, then the match is a simple string match.

• If the right hand side is a reference to a regexp, then the left hand is evaluated .

• If the right hand side is a code reference, then it is called in a boolean context with the left hand side being passed as an argument.

• If the right hand side is an object which provides a MATCH method, then it this is called as a method, with the left hand side being passed as an argument.

• If the right hand side is an object which overloads ~~, then a true smart match is performed.

• If the right hand side is an arrayref, then the operator recurses into the array, with the match succeeding if the left hand side matches any array element.

• If any other value appears on the right hand side, the operator will croak.

If you don't like the crazy Sub::Infix operator, you can alternatively export a more normal function:

   use v5.10;
   use match::simple qw(match);
   
   if (match($this, $that))
   {
      say "$this matches $that";
   }
