To quote the message which started the thread:
*I think something like sync.Map[string]linked.List string is more readable
than sync.Map[string, linked.List[string]].*
*I propose putting the last type parameter to a generic type after the
square brackets and omitting them when there is only one type parameter.*
I accept it was talking about type parameters to types, not type parameters
to functions (although it would be weird if they were different).
But even if you think only about types, it doesn't make much sense to make
the last type parameter distinct from the others. Another silly example:
# current
type Circle[T1,T2 any] struct {
x,y,radius T1
color T2
}
type myCircle Circle[float64,string]
# proposed
type Circle[T1 any]T2 any struct {
x,y,radius T1
color T2
}
type myCircle Circle[float64]string
