List of mixins

[alippai]

In the readme there is a short section about applying multiple mixins:

Applying multiple mixins in one class declaration will be common, so we could offer special syntax for a list of mixins:

class C extends A with M1, M2, M3 {}

Can I write the example below, so are they treated as expressions?

class C extends A with (1, M1), M2, M3 {}
