editor support for php type hinting and phpdoc method comments goes a long way. intellij can do significant refactors and and searching. you'll get real time feedback for violating types. it's not quite the same as a explicit compile step but pretty close

Komodo IDE helps with that, but I personally switched to HHVM and have a simple bash script that swaps the `<?php` for `<?hh` and back, so that `hh_client` can statically tell me about problems, even when I'm not using any of the Hack features. Works a treat, to be honest!
