DIP 1005 provides new syntax to make it possible to avoid global imports.

Any thoughts?

I like it!

template imp(string mod)
{
  mixin("import imp = " ~ mod ~ ";");
}

auto fun_time(imp!"std.datetime".SysTime tm)
{
  return tm;
}

void main()
{
  import std.stdio;
  import std.datetime;

  fun_time(Clock.currTime()).writeln;
}

I don't understand why we can't use a template like:

auto fun_time(SysTime)(SysTime tm)
{
    import std.datetime;
    static assert (is(SysTime == std.datetime.SysTime));
    return tm;
}

void main()
{
  import std.stdio;
  import std.datetime;

  fun_time(Clock.currTime()).writeln;
}

I think I missed something.
