Hi team,
I wanted to provide some feedback on the syntax used in the generics
proposal.
When I first opened the Go 2 playground, it took me a while to realise that
(type T) was a generic parameter and not a function parameter and that (s
[]T) was a function parameter and not a return parameter):
func Print*(type T)(s []T)* {
for _, v := range s {
fmt.Print(v)
}
}
I think this would start to look more confusing when there are return
values (either single or multiple):
func Something*(type T)(s []T) (T, T)*
I think another character would server to improve the readability of the
Print function in this example and hopefully prevent the time required to
grok a generic function to someone who has not seen one in Go before:
func Print*<type T>(s []T)* {
for _, v := range s {
fmt.Print(v)
}
}
func Print*[type T](s []T)* {
for _, v := range s {
fmt.Print(v)
}
}
Cheers,
Rob
