But static typing only catches *some* of the errors that might
occur. Other errors will occur at run time even with static typing -
so you need to really exercise all possible test cases to make sure
you've covered everything in any case.

Static typing saves you some time by catching a small subset of
programming errors at compile time. On the other hand, it costs you
time by forcing you to declare a type for - well, everything that
you're going to catch errors for.
It's not clear which cost is larger.
