I'm pretty sure the cost of checking this in a static language where the tag enums range is known at compile-time is:
- 100x cheaper than cache-miss on a memory access
- and 10000x cheaper than IO which is often where those errors/results/maybe/exceptions issues arise.
I.e. irrelevant in most cases.
