For some definition of "instant".

I can often run my Python or JavaScript test suite faster than Haskell/GHC or Rust/rustc can type-check a module.

And it can take a while to understand Haskell, Rust, or C++ error reports.

(Of course, Python and JavaScript startup time and execution speed can hurt refactoring too. And AttributeError-s and random undefined-s aren't always easy to debug.)
