const_missing

[Hal E. Fulton]

I just tried to use const_missing (which I think is a
neat idea).

Shouldn't it work at the top level? Am I doing something
wrong?

def const_missing
"not found"
end

p FOO

The above gives an error.

This should be

---
def Object.const_missing(sym)
p sym
end

On second thought your implementation could
have worked - the following may sheet more light
(confusion in my case;-) on it ...

--
def const_missing(sym)
p sym
end

def const_missingx(sym)
p sym
end

public :const_missing,:const_missingx
Object.const_missingxK) # :K
Object.const_missingK) # throws a NameError ???
