Consider `tests/ui/const-generics/generic_const_exprs/issue-102768.stderr`, the error message where it gives additional notes about where the associated type is defined, and how the dead code lint doesn't have an article, like in `tests/ui/lint/dead-code/issue-85255.stderr`. They don't have articles, so it seems unnecessary to have one here.

// All lifetime parameters in struct constructors are currently considered early bound,
|
|
// i.e., `S::<ARGS>` is interpreted kinda like an associated item `S::<ARGS>::ctor`.
|
|
// This behavior is a bit weird, because if equivalent constructor were written manually
|
|
// it would get late bound lifetime parameters.
|
|
// Variant constructors behave in the same way, lifetime parameters are considered
|
|
// belonging to the enum and being early bound.
