This looks really clean for code modularity.

import io = std.stdio : {writeln, write}, ...

What does this add? A line like below would be confusing.
import io = std.stdio : {writeln, write}, writefln;

The following code compiles and the imports are less 
confusing.

import io = std.stdio : writeln, write;
import std.stdio : writefln;

void main()
{
    io.write("foo");
    io.writeln("bar");
    writefln("My items are %(%s %).", [1,2,3]);
}

Its more like this:

import oo = {std.stdio : {writeln, write}, std.algorithm: 
{filter, map}, …};

oo.writeln();
oo.write();
oo.filter(...);
oo.map(...);


private struct oo{
    import std.stdio: writeln, write;
    import std.algorithm: filter, map;
    // …
}

void main(){
    oo.write("result: ");
    
oo.writeln(oo.map!(x=>x/2)(oo.filter!(x=>x%2==0)([1,2,3,4,5,6,10])));
}

Wow, that might solve the problem! A little more verbose but it 
does combine everything.

Any downsides?

Thanks.
