about import module

[timi5691]

in A module, i import math module.
in Main module, i import A module.

How i can use math module's functions and types in main module without have to import it again?

Only way would be to have wrappers for the math module's functions in A.

A lot of work to avoid a simple import math.

Note, that even though both your Main and A modules import math, the code in math will be processed just once, i.e. you can import it whenever it is needed (and in fact you have to), V will ensure, that there will be no duplicate symbols because of it.
