The control flow analysis improvements look awesome 👏. Will it also work if we destruct `kind` in the function declaration, like so?: function area({ kind, …shape }: Shape): number
How can changing the type of the catch variable from `any` to `unknown` not cause a major version bump as it's a breaking change? I upgraded to 4.4, recompiled, and got errors. I fixed them, but still. I should be able to upgrade without touching anything else.
Yes! 4.5 roadmap looks great too, excited for the profiler / tracer upgrades!
The new capabilities for control flow analysis of aliased conditions and discriminants is fantastic! Great job 👏
What I'd really like to see is an alternative --strict flag that enables all the sane flags like --noUncheckedIndexedAccess, since the count of these good but non-strict flags seem to be increasing
