This, times a million. I had already been thinking about it.
*I would like to solicit unit test contributions from users of the plugin*,
following this format:
- Exported as JSON or TID
- Tagged "UnitTest"
- Text is a formula in (= mushroom brackets =) that should produce TRUE
- Title Format:
- For functions: UnitTest/Functions/<function_name>/<test_name>
- For operators: UnitTest/Operators/<operator_name>/<test_name>
- For other stuff: UnitTest/Other/<test_name>
In other news I'm realizing that selective evaluation is going to be
necessary for IFERROR to work at all, and to efficiently implement things
like IF and SWITCH which shouldn't be computing the arguments they don't
use. In the long term I expect to explore some aggressive optimizations
for formulas, depending on what uses I put it to.
