Ceylon uses „&" for intersection types, i.e.
SomeRealClass & SomeProtocol
and the bar („|“) for union types, i.e.
String | Int
That has proven to be very lightweight and readable in Ceylon where it is
heavily used to good effect.
I agree with you that
type<SomeRealClass, SomeProtocol>
is much nicer than protocol<> for intersection types but to keep the door open
for union types, I would prefer
all<SomeRealClass, SomeProtocol>
This would allow
any<String, Int>
to be used for union types.
