Oh, this is so easy in MOO code[1], it's not funny:

{{`tostr(args[1], " + ", args[2], " = ", args[1] + args[2]) ! ANY =>
"that's an error"'}}

(yes that's a backquote at the start and a normal one at the end.
Semantics of "+" may differ from what you intended.)

In VB.NET:

{{Try
    Return Arg1 & " + " & Arg2 & " = " & Arg1 + Arg2
  Catch e as Exception
    Return "that's an error"
  End Try}}

(Ok the typing is probably wrong.)
