## TODO

Some ideas for future benchmarks:

- [ ] [SearchValues](https://learn.microsoft.com/en-us/dotnet/api/system.buffers.searchvalues-1) vs Regex and other Alternatives

- [ ] [UnsafeAccessor](https://learn.microsoft.com/en-us/dotnet/api/system.runtime.compilerservices.unsafeaccessorattribute) vs Reflection-Based Access

- [ ] [Source Generated Regex](https://learn.microsoft.com/en-us/dotnet/api/system.runtime.compilerservices.unsafeaccessorattribute) vs Regular Regex (in various manner: static, instance, compiled, ...)
