Check if a parameter is a constant or an object?

Ruby

Hi all

def some_method(arg)

How do I check here if arg is a constant or an object?

end

Thanks :slight_smile:

arg.is_a?(Class) || arg.is_a?(Module) ? “class/module” :
“object/number/whatever”

Constants are bound to objects:

X = “hi”
some_method(X)

The method just receives an object reference. It doesn’t actually
receive a constant; the constant is just an identifier.

(Or am I misunderstanding?)
