I think notInifnite is too contrived, you would always just use 
`else` there. This is more realistic:

int notInfinite(in int b) pure nothrow {
     if (b < 0)
         return 10;
     if (b > 10)
         return 20;

     // In release mode this becomes a halt, and it's sometimes
     // necessary. If you remove this the compiler gives:
     // Error: function test.notInfinite no return exp;
     //    or assert(0); at end of function
     assert(false);
}

What about:

static ~this() { "asdasdasd".writeln; }

?

Static destructor is called!

Application output:
spam at exit
bar at exit
foo at exit
Never called

Well, we have a little mystery here :-) Using both the latest 
beta of ldc2 and the latest alpha of dmd, on Windows32 I don't 
see "Never called" called :-) Perhaps this incongruence is 
another little compiler bug? :-)

I think so. On dpaste using 2.063.2 or git version that function 
isn't called. Only on 2.065..

More:
import std.stdio;
"Never called".writeln;

This doens't work on git version (only in 2.065). I think it is a 
known behaviour about "local" import + ufcs. Why does it work on 
2.065?

The C exit() function is not required to honour D module 
destructors.

This code should work (because the imported names are not locally 
defined), and it correctly works with the latest dmd alpha :-)
