Jonathan's idea might also be encapsulated in a function, just 
like assumeUnique in Phobos:

import std.stdio;

template unsafe(alias fn) {
     @trusted auto unsafe(T...)(T args) {
         return fn(args);
     }
}

@system void fun(int n) {
     writeln("foo!");
}

@safe unittest {
     unsafe!({
         fun(2);
     });

     unsafe!fun(2);
}
