| Subject: | Unprominent caveats |
The documentation is complete, but the caveats are so subtle that it
would be very helpful to mention them already in the synopsis,
something like:
subtype ArrayRefOfPositiveInt, # No "=>" here, avoid stringyfication
as ArrayRef[PositiveInt];
has 'baz',
isa => NegativeInt, # No quotes here, it's now a function call
is => 'rw';
