Seemingly unsolvable level equation

Aya version: latest build (e4948a9) from GitHub Actions

Code:

struct TypeStruct : Set
  | type : Set

def setType (type' : Set) (ts : TypeStruct) : TypeStruct
  => new TypeStruct { | type => type' }

Got error:

In file code/test.aya:5:9 ->

  3 | 
  4 | def setType (type' : Set) (ts : TypeStruct) : TypeStruct
  5 |   => new TypeStruct { | type => type' }
           ^--------------------------------^ TypeStruct.u <= TypeStruct.u

Error: Cannot solve some level equation(s)

There seems no way to solve this error.

PS. Will there be a syntax for struct updating like in Idris? PS2. Will there be partial implementation like in Arend? PS3. Do my issues feel spamming?

Checkout the latest version. The level error is reported beforehand now.
