Module.nesting for anonymous modules?

Hi list,

I’m trying to get a reference to the module that a method is defined in,
problem being that the module is generated dynamically so is not part of
the
AST.

foo = Module.new do
def m
Module.nesting
end
end
=> #Module:0x28879c4

c = Class.new { include foo }
=> #Class:0x287164c

c.new.m
=> []

Is there any way for a method defined like this to get a reference to
its
containing module?
