I disagree. Static typing in essence gives you a lot of small unit
tests for free. When refactoring code, these tests are often
sufficient to ensure that the refactored code works. (Other types of
errors are usually weeded out in the unfactored code, and not
introduced by refactoring)
Static typing also gives you the flexibility to juggle compositions of
higher order functions; I almost always commit type errors when
constructing a largish expression, but when the type errors are weeded
out, more often than not the expression works as expected.
All IME, of course.
If I haven't seen further, it is by standing in the footprints of giants
