I wondered about the inclusion of char! as an argument type as
well, and then thought to try

== 0
>> #"^@" - 1
== #"ÿ"

Aha! I thought that Ladislav is very clever to include a type that
can exercise at least two legs of the three-legged stool. Then I
read your post...

...and (confirming the change of notation, just for formality)...

== true

== true
