[stack] Applicative Syntax == Concatenative Syntax

Consider if we were to define our stack-based (concatenative)
functions as quotations such as:

  define Add { [+] }

We can define the open paranthesis, close paranthesis, and comma as follows:

  define ( { }
  define , { curry }
  define ) { curry eval }

This allows us to write:

  Add(2, 3)

Which leaves the value 5 on the stack just as we would like to see.

I've implemented this in the most recent version of Cat (which I have
posted at http://www.cat-language.com/cat.zip , but haven't officially
announced yet).
