Fallout: tests. As tests frequently elide things, lots of changes here. Some of this may have been poorly rebased, though I tried to be careful and preserve the spirit of the test. 2015-02-12 15:29:52 +00:00			`use std::marker;`

diagnostics: remove inconsistent English article "this" from E0107 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. 2023-02-23 17:27:06 +00:00			`//~^ ERROR struct takes at least 2 generic arguments but 1 generic argument`
