Who own the constants?

[rolo]

Hi

Who keeps the constants defined within a Module of the Class?

The Class in which it is defined or the last module in the class hierarchy ?

What do you mean by "Module of the Class"?

The Class in which it is defined or the last module in the class hierarchy

?

Constants are always owned by the module or class they are defined in
although they are accessible from modules / classes that inherit the
defining class:
NameError: uninitialized constant Mod::FOO
from (irb):6

Foo.ancestors => [Foo, Mod, Object, Kernel]
Foo.constants => ["BAR", "FOO"]
Mod.constants

=> ["BAR"]
