This first compares the Repr before falling back to actually comparing the raw as_str itself. In some micro-benchmarks, this speeds up inline and heap string comparisons when equal by ~70%.
There is a tiny hit in the non-equal case however. It is also noteworthy that the assembly generated for Repr is horrible, and looks like its above the inlining threshold now.
