autoload? 

        # Module.autoload?

(from ruby core)
---
    mod.autoload?(name, inherit=true)   -> String or nil

---

Returns *filename* to be loaded if *name* is registered as `autoload` in
the namespace of *mod* or one of its ancestors.

    module A
    end
    A.autoload(:B, "b")
    A.autoload?(:B)            #=> "b"

If `inherit` is false, the lookup only checks the autoloads in the
receiver:

    class A
      autoload :CONST, "const.rb"
    end

    class B < A
    end

    B.autoload?(:CONST)          #=> "const.rb", found in A (ancestor)
    B.autoload?(:CONST, false)   #=> nil, not found in B itself
