I don't understand why Smalltalk doesn't allow me to have an or: method that takes a block argument (except on Boolean). For example:
Set or: 1. ==> MNU as expected.
Set or: [1]. ==> NonBooleanReceiver exception.
Set or: [:x | x] ==> Argument has too many arguments
Is it because the compiler specializes this to boolean when it sees the or: [ ... ] syntax? Is this a tradeoff made for performance?
