For example, Go 1.21 introduces the `panicnil` setting,
controlling whether `panic(nil)` is allowed;
it defaults to `panicnil=0`, making `panic(nil)` a run-time error.
Using `panicnil=1` restores the behavior of Go 1.20 and earlier.

When compiling a work module or workspace that declares
an older Go version, the Go toolchain amends its defaults
to match that older Go version as closely as possible.

Revenons un peu en arrière et comprenons de quoi il s'agit.

Le « flux » `password` est l'une des manières (« flows ») définies dans OAuth2 pour gérer la sécurité et l'authentification.
