Classification:Enhancement Reproducible:Always
 
Summary:
I want to be able to define generic typealiases. For example:

typealias Cons<First, Rest> = (First, Rest)

Hereafter I’d be able to use Cons<X, Y> to refer to a specific instance of this tuple type family.


Steps to Reproduce:
Try to compile the above typealias.


Expected Results:
I didn’t actually expect it to work, but I would like to be able to expect it to work.


Actual Results:
It didn’t work, of course.


Regression:
N/A


Notes:
This would go a long ways to being able to use tuples as first-class types.
