Error: The conclusion of a builder is a mixin whose parameters depend on other mixins

[SamuelArsac]

I have this error when trying to define an instance using a factory. Using a different factory for the same structure gave me a similar error.

I haven't been able to reproduce the error on a smaller example.

Here is the file where this happens (the instance definition is a the very bottom).

Linked to issue #432.
