That has literally nothing to do with what the parent comment is talking about. And that's not naivety either. That's because the way type inference, operating overloading, and literals work together ends up being a combinatorial explosion.
As usual, compile times depend on what you're used to. It is something we're working on improving though; we want it to be very fast! We expect incremental recompilation to move out of nightly soonish; that will help quite a bit.
