Language experiments (#2068)

* #include an absolute path didn't work - because paths were taken to always be relative.

* Moved to experiments.
Added some more tests.

* More tests around associated types.

* Return interface tests.

* More tests.

+.slang(5): error 30019: expected an expression of type 'int', got 'typeof(SIZE)'
+    T elements[SIZE];
+
+Problem here is SIZE doesn't have *let* in front. The error doesn't provide any useful insight into that. It's also not entirely clear *why* let is needed. Presumably because it's not a type?
