Importing a lot of stuff from a deeply nested modules is very annoying because it needs a lot of repeating, for example:

import really.very.deeply.nested.package.module1;
import really.very.deeply.nested.package.module2;
import really.very.deeply.nested.package.module3;

Allowing selective import syntax to do this in a more concise way would be a great improvement over this, the above example could be rewritten as:

import really.very.deeply.nested.package: module1, module2, module3;

Maybe this should be semantically equivalent to this instead of the first example:

import module1 = really.very.deeply.nested.package;
import module2 = really.very.deeply.nested.package;
import module3 = really.very.deeply.nested.package;

It can be a little more consistent with selective imports. But we still have to same problem if we don't want to type module1.symbol and want to type just symbol instead.

Maybe a new syntax can be introduced to allow that, like:
import really.very.deeply.nested.package { module1, module2, module3 };

Or something similar.

I think this is the way to go, and is very commonly useful.

> import really.very.deeply.nested.package { module1, module2, module3 };

I don't think it's worth allowing both selective modules and selective symbols in the same statement. Importing selective symbols from a module can just use a separate statement, and it's less common than full module imports anyway.

I'd like to write:

import std: stdio, algorithm, range, array;
