go vet proposal targets empty-struct map keys

A new vet proposal wants to flag `struct{}` and `*struct{}` used as map keys, on the grounds that pointer comparability makes the pattern tempting but rarely what the author meant. It is a small lint, but the kind that tends to surface real bugs once it lands. On the writing side, there is a piece arguing Java microservices can now match Go on a 2026 benchmark, which should generate the usual round of methodology arguments, and a Stackademic post on Docker conventions the author has stopped copying into every project. Over in the questions pile, someone is wrestling with how to mirror a nested C struct across the cgo boundary, which is one of those problems that never gets easier the second time.

Proposal Details Pointers are comparable, and structs are often used as map keys, so a developer could be tempted to use an unique pointer as a map ke

How should I represent a C struct in Cgo?

So I have a struct defined in C, which contains some other C structs, pointers, etc. So do I create a 1-to-1 mapping go struct, and do conversion every time I need to call C functions. Or do I simply
