zod doesn't work with typescript `4.3.2`

[KATT]

see #472

Ran into the same issue today when updating packages.

Keeping typescript at 4.2.4 works for now as a workaround.

Thank you for filing this issue and giving a workaround which saved us some tzores.

Can confirm that pinning TS to 4.2.3 solved our problem.

For anyone Googling, this is the error we got:

Excessive stack depth comparing types 'ZodError<?>' and 'ZodError<?>

workaround in my monorepo: trpc/trpc@ff184a9

I also experienced the same issue. Reverting to TS v4.2.4 solved it for now.
Here are the errors I see. Hope it helps!

Ps. Love the library, keep up the awesome work!

Hi guys. This has been raised on microsoft/TypeScript#44299. There seems to be a more severe variation of this where node runs out of memory during type checking when zod is in use.
