so there are still people...

Just to be clear, I do find in-editor syntax checking a reasonable tradeoff, even though it is sometimes disturbing. It helps that I use vim, where the modality gives reasonably good signals to the editor when it can start trying to compile my stuff (when I exit insert mode).

Also, semantic understanding of the code yields _incredibly_ much better jump-to-definition navigation, which is a huge win, but you don't need to enable any warnings for that, of course.
