[stack] Re: So what is a concatenative language?

The real definition of "concatenative" is semantic: If P and Q are 
sentences in a concatenative language, then so is P Q, and the meaning of 
P Q is the composition of P and Q.  Isn't that the definition that Manfred 
uses?

The definition of "flat" is syntactic, and trickier: a flat concatenative 
language is a concatenative language whose sentencess are all either 
atomic or concatenations of (zero or more) other terms.

This leaves "atomic" undefined.  I can't see offhand what a concise 
definition might be.
