The Scala compiler is excruciatingly slow for me.  I frequently rely on polytypic programming techniques to prove (with a small &quot;p&quot;) that my code is correct.  The compiler simply can&#x27;t keep up with me.<p>The end result is that my state of flow is continually interrupted, or at least under assault.  Bobbling my head to trance music while implicits are resolved is the only antidote that I know of.
