Trivia:
In https://docs.raku.org/type/UInt, a cardinal (uint)
is a subset
Nope. Case matters. It's mixed case "UInt" (not "uint") that's a subset.
Absolutely! uint belongs to UInt
In https://docs.raku.org/language/nativetypes, a
cardinal (unit) gets their own "native type".
… whereas (lower case) "uint" is a native type.
Documentation is easier to understand if you read what it says, and not what you expect it to say.

Hi Erik,
"uint" belongs to "UInt". The error message should tell me one
of the other. I prefer "unit", but will compromise on "UInt".
The ONLY beef I have is with the error message.
What makes you think I did not understand the documentation?
Perhaps it is you who does not understand me?
Oh this is interesting:
https://docs.perl6.org/type/UInt (the raku one is missing the graphic)
"The
UInt is defined as a subset of Int:"
but does not show on the graph.
UInt --> Any --> Mu , but no "Int"
Perhaps better stated would be
UInt --> Int --> Any --> Numeric --> Mu
I may have Mu and Numeric reversed
Documentation is a thankless task and those that do
it are never appreciated.
