Sumário: create a fake infix operator
Descrição:
Sub::Infix creates fake infix operators using overloading. It doesn't
use source filters, or the Devel::Declare manpage, or any of that magic. (Though
Devel::Declare isn't magic enough to define infix operators anyway; I
know; I've tried.) It's pure Perl, has no non-core dependencies, and
runs on Perl 5.8.
The price you pay for its simplicity is that you cannot define an
operator that can be used like this:
my $five = 2 plus 3;
Instead, the operator needs to be wrapped with real Perl operators in
one of three ways:
my $five = 2 |plus| 3;
my $five = 2 /plus/ 3;
my $five = 2 <<plus>> 3;
The advantage of this is that it gives you three different levels of
operator precedence.
You can also call the function a slightly less weird way:
my $five = plus->(2, 3);
