I think the discomfort I felt at looking at that was because of the stylistic difference. There isn't any part of it that looks terribly hard to understand when compared to other code. I presume anyone dealing with this codebase would know what ctx entails and most things seem to logically flow from what it provides.

I think if I dealt with this on a daily basis I might end up finding if vastly more preferable, albeit at the risk of alienating fellow developers. In that respect it seems much like learning to use Emacs or vi
