Julia 1.12 unsupported

[AntonReinhard]

Unit tests fail on 1.12

Running the tests locally on the current nightly fails, see below. The nature of the error seems to imply that it's not just some temporary regression on nightly, but an actual issue.

The syntax: malformed expression is the same error I'm getting in my own project trying to call a RuntimeGeneratedFunction.

Expected behavior

The tests should succeed and RGFs should be callable.

Minimal Reproducible Example 👇

using Pkg
Pkg.test() # with julia +nightly --project
