### ShellError size rework - larger topic of performance engineering
- Piepmatz has valiantly worked on getting ShellError smaller
- tradeoffs for usability
- different compact string types with slightly different APIS
- Boxing particular parts/the whole shell erro has its pros and cons (especially usability cons).
- Any work that aims to improve performance needs to show its benefits and should be measured by benchmarks etc.
- For larger systems: don't microoptimize for one thing but bring a general improvement
- Need to make a decision on some trade-offs (one use favored, another pessimised).
- Have a broader collection of benchmarks to be aware of those trade offs when making larger changes (for smaller optimization reasonable assumptions with singular benchmarks can be made)
