You are right when it would only be about Forth, but we were musing about
simplified compilation without all the usual ballast.

So the capability in a (meta)language for compile-time execution comes into play.
Forth is only one example. TCL would be my next candidate. I don't know Seed7
but its author claims to be able to e.g. redefine and create new operators which
means new semantics.
[There was a vogue in the 1970s for extensible languages like EL1 at Harvard
and IMP72 at Yale.  You could add new grammar rules on the fly.  What that
meant was that no two programs were written in the same language and they were
unreadable and often undebuggable.  OOP, which lets you add new types and
semantics without changing the syntax, turned out to be a lot more useful.
See https://en.wikipedia.org/wiki/Extensible_programming -John]
