Two things that immediately come to mind:

- `unittest`. Clutters code reading, discourages extensive 
testing (because of said clutter), discourages testing inside a 
user's module, complicates runtime and compiler, framework cannot 
be developed separate from language runtime, ...

- Implicit pointer/reference type of classes. While I think the 
forced reference type of classes is a good idea (when passing as 
function argument), I think it was a very bad idea to remove the 
`*` from notation. It makes code impossible to interpret without 
looking up a user-defined type.
