Oh crud,

class A
def initialize
@b = B.new
end
def method_missing(s, *a, &b)
@b.__send__(s,*a,&b)
end
end

class B
def method_missing(s,*a,&b)
"HERE"
end
end

A.new.foo

How to get "HERE"?

Works for me.

I just had to `puts A.new.foo`

My bad, I mistook my trouble for this issue. But actually the trouble
only arises when:

class B
def method_missing(s,*a,&b)
"HERE"
end
private
def foo; 'foo'; end
end

Because method_missing applies to public calls and ignores private
ones.
