[0.19.0] - 2022-06-22

Added

• table.insert(x) no longer counts as a read to x, which allows selene to alert you that you are only assigning to it.
  • This is done through a new standard library field for arguments called observes. This takes 3 values: "read-write" (the default), signifying a potential read and write, "read", signifying only a read, and "write", signifying only a write. Only "write" has meaning at this time.
• Added new must_use lint, which will warn you when you are not using the return value of a function that performs no other behavior.
  • This is done through a new standard library field for functions called must_use. Set it to true to gain this functionality.

Fixed

• Fixed a bunch of performance failures, lowering some benchmarks from 3 seconds to 200ms.
