This avoids a weird "unknown feature `proc_macro_span_shrink`" error that occurs somewhere in the proc-macro2 crate. I think this is the relevant issue: dtolnay/proc-macro2#356 Pinning the exact compiler version seems like the only way to avoid this sort of dependency churn when using nightly features. This can be manually updated in the future, assuming related compilation errors are fixed.
