Codegen error when converting from set of range of integer to set of integer

[metagn]

Example

var x: set[range[1u8..5u8]]
x.incl(1)
x.incl(3)
x.incl(5)
echo set[uint8](x)

Current Output

/usercode/nimcache/@min.nim.c:161:44: error: cast specifies array type
  T1_[0] = dollar___TUG7TzrD5Kd6aiBLNBckQA(((tySet_tyUInt8__k3HXouOuhqAKq0dx450lXQ) (x__EGWKGClUlppqAonIP2rgfg)));

Expected Output

{1, 3, 5}

Additional Information

• Most likely the master issue of Codegen error when operating on sets of a type and of a range of the same type #15435, Wrong C code generated on operations on sets #16269, Wrong result on operations on sets of different types #16270. Not directly related to C Error on invalid uint -> set cast #3540 as this issue performs a cast, not a conversion.

$ nim -v

It now gives

 type mismatch: got 'set[range 1..5(uint8)]' for 'x' but expected 'set[uint8]'

Weird but separate issue
