Dereferencing a ref type does not compile

Dereferencing a ref type does not compile

No suitable [] implementation is found for the reference type itself. Derefencing an instance works.

Example

type
  MyType = object
    a: int
    b: int
    c: int
  
  MyRefType = ref MyType

echo compiles(MyRefType[])

Remark: the compiles proc checks whether MyRefType[] compiles. As it generates false as output, it does not.

Current Output

false

Expected Output

true

Possible Solution

Additional Information

The issue came up in this thread on the Nim forum when discussing how to get the size of the underying type of a ref.
