Reminded me that we don't have a property for Morse code.

If it is to apply here, it is not a property for morse code we need. We need a datatype. /ℇsquilo 14:26, 11 August 2018 (UTC)

This property could be translated into morse code with the new property. I agree that current datatypes aren't optimal for morse code (see discussion in the proposal).
