(Better to avoid revised syntax in such cases, it is confusing here)

I was not aware of that, but this is logical since the problem comes
from expansion, and simple variants do not need to be expanded.
So I should correct my phrasing: explicit polymorphic type variables
inside constrained type parameters of type abbreviations are not
supported.
