Thank you for the pointer and explanation.

Does anybody know exact conclusion of the discussion
on ABC::load('abc-point') syntax?

My memory is blurred, and if I remember correctly,
the suggestion was rejected because ABC::load syntax
does not anything but

require 'abc-point'

module ABC
   include abc-point
end

and such an implementation is already there and trivial.

And I am curious why namespace capability is not part of
Ruby language. Is there any standardized solution for
handling two 'Point' classes from two different company?

Sincerely,
Minkoo Seo
