On hxcs, the only type parameters allowed to be declared are the basic c# types.
That's made like this to avoid casting problems when type parameters in this case
add nothing to performance, since the memory layout is always the same.
To avoid confusion between Generic<Dynamic> (which has a different meaning in hxcs AST),
all those references are using dynamic_anon, which means Generic<{}>

Because Null<> types need a special compiler treatment for many operations (e.g. boxing/unboxing),
Null<> type parameters will be transformed into Dynamic.
