You might be missing the fact that when I call a function as a function, 
and not a method, it doesn't suggest any imports.

This problem doesn't happen with writeln:

void main()
{
     writeln("hello, world");
}

Error: writeln is not defined, perhaps import std.stdio; is needed?

I expect the compiler to suggest an import of std.conv when I use `to` 
in the *same way*.

I don't have any idea what you mean. You mean, the feature to suggest 
imports is useless? There's no way to fix it?
