This bumps the `th-desugar` commit in the `cabal.project` file's `source-repository-package` to bring in the changes from `th-desugar-1.17`. Among other things, this version of `th-desugar` adds support for: * Namespace specifiers in fixity declarations * Embedded type expressions and patterns * Invisible type patterns For now, `singletons-th` will error if it encounters any of these constructs. Where appropriate, I have opened issues to track the idea of supporting these language features in `singletons-th`: * For namespace specifiers in fixity declarations, see #582. * Supporting embedded type expressions and patterns seems quite difficult due to `singletons-th`'s policy of only promoting/singling vanilla type signatures (see the `README`), so I have not opened an issue for this. * For invisible type patterns, see #583. This is one step towards preparing a GHC 9.10–compatible release of `singletons` and friends (see #569).
