model oriented programming

[Matt Maier]

So, Livecode is a scripting language. Whatever logic and data I string
together in LCS is converted by the engine into equivalent code in
languages like C. Does that make the LC engine a code generator? Seems like
it does.

These guys take it one level farther back and start with a model which
defines a code generator which then creates code.

I'm trying to wrap my head around it.

They also use their code generator to generate their code generator.
