Minor Description
I suggest adding a backwards-compatible StarGraph builder exposing a couple minor performance-sensitive behaviors for configuration.
Specifically:
- StarGraph calls String#intern on labels
- StarGraph calls Object#toString on ID elements when testing element-existence-by-id
It would be nice to have the option to disable these calls in use-cases that don't need them. Disabling the former needs no explanation; disabling the latter would cause cases where element IDs are first toString'ed and then equals-checked to jump straight to the equals check. The performance gain is going to be small and bound to a narrow set of applications, but it's nice to have the choice. It shaved about 3~5% runtime off the use case-case that led me here (via profiling).
I already tested a local change that adds a builder while neither modifying StarGraph's default behavior nor disturbing any of its existing method/constructor signatures. I'll file a PR against tp32 momentarily.
