Consider using UNICODE NULL symbol '␀' for nulls #21

Open pathikrit opened 6 years ago

Char nullSymbol = '␀'

While the semantics appeal to me, I am not convinced, because this symbol is somewhat hard to read in comparison to ∅...

Maybe an option override it then? RefTree.Null(displayAs = "␀"). I can imagine people may want to display it as string "NULL".
