Description Robin Morisset 2018-06-18 09:01:16 PDT

```
typedef a = b;
typedef b = a;
```
currently hangs the interpreter until it has a stack overflow.
Ideally it should be detected, and give a nicer error message.

Other types too: enums, arrays, structs, etc. (I don't know how they could be circular, but we should prove that it isn't possible using any type)
