WOW!! That *IS* cool. Can you explain to me how it works? I figured out postfix: myself, but the rest is obscure to me.

Here is another idea: Is it possible to declare a circumfix function that calculates the magnitude of a vector?

$magnitude = |@vector|;

You know how in math, two vertical bars are a standard notation for magnitude. Oh oh oh... is it possible to define a circumfix function for the dot product? Something like:

$dot_product = <@vector1,@vector2>;

Is that possible? That would be uber-cool.
