Why does not UFCS work for method defined inside unittest block?

[Ky-Anh Huynh]

Hi,

Can I define a new quick function to use inside a unittest block?

I have the following code:

[code]
auto foo(string[] sta) {
   return sta;
}

auto bar(string[] sta) {
   return sta;
}

auto h(string[] sta) {
   return sta.foo.bar;
}

unittest {
   import std.format;

   auto f = (string[] sta) => sta.foo.bar;
   auto g(string[] sta) {
     return sta.foo.bar;
   }

   assert(f(["test"]) == ["test"]);
   assert(g(["test"]) == ["test"]);
   assert(["test"].h == ["test"]);
   assert(["test"].g == ["test"]);
}
[/code]

The last test will fail: Error: no property g for type string[]

Please advise.

Thanks a lot.
