It's a pretty nuanced phrase and difficult to replace. I might make the case that "easy to reason about" <=> "simple" in the sense that Rich Hickey uses it[1] but that doesn't do anything for the verb itself. The phrase has a high correlation with subjects that are themselves highly correlated with smug proponents; functional programming is one of the greater ones of these. Personally I like the phrase. Then again I self-identify as a (non-smug) SmugLispWeenie[2] so of course I like it.
