Strict Mode

Vide has a special mode called "strict mode" which is used for debugging.

The purpose of strict mode is to help ensure stateful code is pure (deterministic and free from side effects) or if there are side-effects, that they are cleaned up correctly.

Vide is set to strict by doing:

local vide = require(path_to_vide)
vide.strict = true

What strict mode will do:

1. Run derived callbacks twice when re-evaluating.
2. Run watcher callbacks twice when a state changes.
3. Throw an error if yields occur where they are not allowed.
4. Checks for map() returning primitive values.
5. Better error reporting and stack traces.

It is recommend to develop UI with strict mode and to disable it when pushing to production.
