> Are you really running your test suite for every "i+=1" change on other languages?

You don't have to run your testsuite for a small bugfix (that's what CI is for), but you DO need to restart, reset the testcase that triggers the code you are interested in, and step through it again. Rinse and repeat for 20 or so times, with various data etc. - at least that's my debug-heavy workflow. If any trivial recompile takes a minute or so, that's a frustrating time spent waiting as opposed to using something like a dynamic language to accomplish the same task.

So you would instinctively avoid Rust for any task that can be accomplished with Python or JS, a real shame since it's very close to being an universal language.
