Concatenative languages are really not esoteric. I mean assembly language is a concatenative language, and it really ought not to qualify as esoteric.

Assembly is pretty esoteric these days... I mean, most every platform no matter how resource constrained has at least a C compiler, and must of 'em probably have a Python interpreter.

> assembly language is a concatenative language

Are most? I've always considered them more procedural than anything else. Variables and gotos.

Concatenative just means that concatenating two programs yields a new program and that is the major method of program construction. Most Forth dialects also support variables, gotos and procedures; but it's all in a concatenative way.

Is that so? According to: https://en.m.wikipedia.org/wiki/Concatenative_programming_la... there's a little more to it.

I suppose if you squint a bit, any push-jump-ret-pop sequence is concatenative - but I'm not sure if I agree that the main way to go from a few general assembly language programs that each read from a file, count words, and sums integers - to a program that counts words in a file is to simply concatenate them?

Once you understand the documentation, other language's documentation becomes easier to understand.
