[CodeSandwich]

Fixes #NONE

It's a really small optimization avoiding hashing strings when they're obviously different.

Thanks for the clear title. 😛

This is definitely good, we just need a changeset. Can you add it (npx changeset add) or let me know if I should do that for you.

I've added the changeset. Sorry for not doing it before, this PR seemed too small to litter the changelog with it, my misake 🤷

BTW you've added this PR to the 5.0 milestone, does it mean that it won't be available in 4.9.1 and 4.10 if such versions ever exist? I'm not a project maintainer, but it seems strange, it's not a breaking change or even a new feature.

• If there ever is a 4.9.1, it will be about bug fixes, not about new features and optimizations.
• We don't plan a 4.10.
• From now on, all features and optimizations are indeed planned to be in 5.0
