> Have the authors considered the implications of requiring the `type` keyword to use a generic type, not just at declaration time? Would this open up more syntax possibilities, such as `var x T<type int>`? This might be easier to read at the expense of five more characters of typing. It also could unify declaration and usage syntax even more than the proposal.
> This might be easier to read Square brackets are easier to read. They are larger and catchier to eyes than lesser and greater signs used as brackets. And type-less syntax with mandatory constraint is even easier and feels like a great match with the rest of the language. четверг, 6 августа 2020 г. в 22:25:19 UTC+3, Red Daly: > Have the authors considered the implications of requiring the `type` > keyword to use a generic type, not just at declaration time?
