Hi! I have two questions.
1) How to declare a stack effect for such function?
: foo ( ?? -- ??? ) dup 5 = [ ] [ drop foo ] if ; inline recursive
2) How the word with-compilation-unit applies changed words?
It's invoked with with-scope word witch discards any variable set by the
quotation.
Question 1 is really simple:
foo is wrong, thus cannot compile :-(
In one case foo expects a number, in the other recurse with empty stack
(with no input parameter).
Even fixing this, if you don't change some other thing, you would have
infinite loop.
This is what you wrote in C(++):
void f(int
