Workaround non-deterministic order for registering syntactic sugar

[cowboyd]

Because the list of syntax sugar is mutable and is appended to from different portions of the codebase, some sugars will not be registered in the right order.

This isn't a long-term fix for the issue, but it does resolve it in the short term.

There are still problems with the syntactic sugar, but now they can be worked around:

before:

class TodoList {
  todos = [Todo];
}

after:

class TodoList {
  todos = create([Todo]);
}
