Nobody seems to have noticed yet, but yesterday I removed the
restriction preventing import declarations from being used in functions.
These now work:
void test1()

import std.c.stdio;
printf("hello world\n");
}
void test2()
{
static import std.c.stdio;
std.c.stdio.printf("hello world\n");
}

I believe this can lead to better encapsulation of code, especially when
using mixins, versioning and other conditional compilation constructs.
Fabulous. std.benchmark already uses the feature, and from a mixin no less:

One interesting aspect of the feature is that if import is used from
within a template, it's not actually imported unless the template is
instantiated.
