Tracing polymorphic method arguments broken

[EliasC]

Compiling the following program on development

class Foo<t>
  def foo(x : t) : void {
    print "Success";
  }

class Bar<t>
  def bar(x : t) : void {
    new Foo<t> ! foo(x);
  }

class Main
  def main() : void {
    new Bar<int> ! bar(42);
  }

gives the C-level error

foo_src/Bar.encore.c:67:37: error: use of undeclared identifier 'this'; did you mean '_this'?
  encore_trace_polymorphic_variable(this->_enc__type_t, _arg_2->f1);
                                    ^~~~
                                    _this
foo_src/Bar.encore.c:46:48: note: '_this' declared here
void* _enc__method_Bar_bar(_enc__active_Bar_t* _this, encore_arg_t _enc__arg_x)
                                               ^

It seems like the C-level self-variable is sometimes called this and sometimes _this. The fix is probably as simple as being consistent with the choice of name (probably _this).

Same one #344, I think.

[EliasC]

I agree! Is it still best to wait for new-ponyrt you think?

[albertnetymk]

Currently, new-ponyrt has been rebased onto dev. Could be merged after disabling tasks, IMO.

[EliasC]

OK, closing this one then.
