These macros are used like expressions, so they should not emit a
semicolon. This is being turned into a hard error in a future release of
Rust.
error: trailing semicolon in macro used in expression position

= warning: this was previously accepted by the compiler but is being phased out; it will become a hard error in a future release!
= note: for more information, see issue #79813 <https://github.com/rust-lang/rust/issues/79813>
= note: this error originates in the macro `dev_err` (in Nightly builds, run with -Z macro-backtrace for more info)
[ I was doubly surprised since upstream made it a deny-by-default lint
a year ago for Rust 1.91.0, and yet we didn't see it; plus I hadn't
seen this in my CI even yesterday.
It turns out this just landed into today's nightly (nightly-2026-07-16,
using upstream commit d0babd8b6):
Link: https://github.com/rust-lang/rust/pull/159222
which says:
"The `semicolon_in_expressions_from_macros` lint previously
suppressed warnings about non-local macros. This masks
a lint that will subsequently become a hard error."
So that explains it. And this is the PR that will make it a hard error
at some point in the future:
Link: https://github.com/rust-lang/rust/pull/159218
Thus starting with Rust 1.99.0 (expected 2026-10-01), we will be
seeing the deny-by-default lint above, so clean it up already.
