My main issue was when making code modifications. If I wanted to add an argument to a function I would have to find and fix tens of calls to that function in order to convince the compiler to infer the type that I wanted so I could use its error messages to find and fix the rest of the calls. In hindsight, I should've written annotations by hand for functions I had to modify.
