Enum as tagged pointer in nimrod

gistfile1.nim

type 
  TPnt = tuple[x,y: float]
  
  TMaybe {.enumSumTyp.} = enum
    None,
    Just = TPnt

var
  x = (x: 45.96, y: 25.25) 
  test = Just(x)

proc `$`(m: TMaybe): string =
  if m == None:
    result = "None"
  elif m == Just:
    result = "Just " & $m[]
  else: 
    result = "something went wrong!"   

echo(test) #Using `$` above
echo(test[]) #Deref
echo(test.y) #Field Access

The next hurdle is to skip the step of creating x first. If the user were to create a Just((x: 45.96, y: 25.25)) directly, I need to create a heap copy.
