It looks normal but it's not documented. It's just that the 
import is not yet known in the scope. It 's like:

void main(string[] args)
{
     writeln();
     import std.stdio;
}

But

void main(string[] args)
{
     writeln();
}
import std.stdio;

works because the symbol lookup succeeds in the parent scope.

For your example to work, another semantic pass would necessary.
