in reply to Re^2: Prototype like sort()?
in thread Prototype like sort()?

Nice!

to elaborate further, the trick you are using is that prepending & to a sub let's the parser ignore the prototype.

> perlsub: Not only does the & form make the argument list optional, it also disables any prototype checking on arguments you do provide. This is partly for historical reasons, and partly for having a convenient way to cheat if you know what you're doing.
