expected behavior of "require" related to global env

[Gaspard Bucher <gaspard@...>]

Hi there,

I am preparing a first release of some core parts of lubyk and cannot decide what is expected of "require" concerning global environment:

========= A (alter global)

local foo = require 'lub'

print(foo, lub)

--> table, table

========= B (do not touch global)

local foo = require 'lub'

print(foo, lub)

--> table, nil

========= C (do not touch global)

require 'lub'

print(lub)

--> nil

B and C are the same (just two common ways of using "require"). I feel that not touching global creates unexpected behavior in "C".

I feel "A" is the best solution but would like some community feedback on this...

Thanks for your feedback,

Gaspard
