Inline Records show ...printing not supported...

[albertoforni]

Hi and thanks so much for your work!!!

When using inline records on a variant type I see "printing not supported"

type variant =
  | First(string, int)
  | Second({str: string});

let parse = variant =>
  switch (variant) {
  | First(str, int) => print_endline("first")
  | Second({str}) => print_endline("second")
  };

Do you think it can be worked out, or there is some sort of limitation that makes it not possible?
