The bootsnap precompile command tries to precompile all Ruby files under the gem lib/ folders, even those not matching your Ruby version (and, thus, not used in production). We cannot fix this at our end (and should not, since there is no issue or bug). The only workaround is to exclude these files from precompilation:

bundle exec bootsnap precompile --gemfile --exclude 'anyway/tracing|anyway/auto_cast|anyway/type_casting|anyway/config|' app/ lib/

# or simpler (not a big deal excluding a small library)
bundle exec bootsnap precompile --gemfile --exclude 'anyway/' app/ lib/

Doesn't this imply an upcoming breaking change in this gem for 3.4 though?

Edit: I guess if the expected behavior is that "calls without arguments [should] refer to the first block param" for these lines of code then there is no breaking change.

"calls without arguments [should] refer to the first block param" for these lines of code then there is no breaking change.

Yep, correct. We use it intentionally as the first argument; so, in Ruby 3.4 the original source files would be used (right now the transpiled ones are loaded).

Gotchu, thanks!
