There are plans to change the rules for implicit promotion such that calls to
const fnare not implicitly promoted to'staticlifetime any more. A crater experiment showed that only very few crates would be affected by this change, and this is one of them.This PR adjusts the code to no longer rely on implicit promotion, by explicitly putting the result of the function call into a
constitem. Long-term, there will be the possibility of using inline const expressions instead, which will be more ergonomic.
