I think, if I want int/int, I should use int/int or just declare a domain specific alias. MyInt/MyInt should implement Lesser/Min/etc interface. It can declare specific comparison rules.
Min implementation can be like: https://go2goplay.golang.org/p/Fgo2fJAlKXD (this code does not compile, I don't know why) My point is that this decision is not Go1-like and can cause unexpected runtime errors. суббота, 27 июня 2020 г. в 23:03:25 UTC+3, Ian Lance Taylor: > On Sat, Jun 27, 2020 at 12:35 PM a b <tanc1...@gmail.com> wrote: > > > > Newtype is a expression like > > type MyInt int > > > > It's not the same type as int, so why it's permitted? > > In Go1 you must perform explicit conversion. > > Because if you have a MyInt, it would be nice to be able to pass > that to a function like slices.Min.
