Interesting to know, I'd naively guess the opposite. Can you please 
share the source data set? Thank you.


In the standard library, the most notable packages that add generic 
functions are slices  and maps 
. Almost all of their functions feature an 'any' 
constraint. Same for other generic additions to the standard library such 
as atomic.Pointer, reflect.TypeFor, and sync.OnceValue.

The feedback was not specific to the "SumIntsOrFloats" example in the 
tutorial. The tutorial fails to demonstrate any generic data structures 
utilizing the "[T any]" constraint or a function with an 'any' constraint, 
such as "slices.Clone[S ~[]E, E any](s S) S". This omission is notable 
considering "any" is among the most frequently used constraints in writing 
generic code.

I don't understand your feedback. How, exactly, should generics handle the 
`any` type? Documentation can always be improved but how would a generic 
function that accepts two `any` types perform addition of those "any" 
values?

[go-nuts] Unhappy with the official generics tutorial

['Carla Pfaff' via golang-nuts]

The Go documentation, available at https://go.dev/doc/, features only one 
tutorial dedicated to generics, found at 
https://go.dev/doc/tutorial/generics. This tutorial lacks any examples 
employing the 'any' constraint, nor does it mention it. Instead, it begins 
with the use of an 'int64 | float64' constraint. These A|B constraints 
represent a more specialized application of generics, aimed at scenarios 
where there is a need to utilize an operator such as "+". However, the most 
universal, adaptable, and reusable form of a generic type or function — one 
that utilizes 'any' — is notably absent.
