Making top level definitions in REPL

I would like to define a recursive function in DAML REPL, but I get error

  Failure to process DAML program, this feature is not currently supported.
  Local variables defined recursively - recursion can only happen at the top level.

Is this currently possible?

At the moment no, let in DAML REPL is equivalent to let anywhere else in DAML so it’s not a top-level definition.
