What are some considerations for when rum/defc cannot pre-compile the hiccup defined within a component? We're looking to minimize the amount of hiccup intrepretation at runtime. Any helpful hints on building a better intuition around this? from https://github.com/tonsky/rum/blob/9feb2a1781e3ef716361f9788150a01ea7f791b6/doc/optimizations.md > In Rum for example, where most of the Hiccup is pre-compiled into React calls via defc macro the perf hit is lower than in Reagent, thus the possibility of usefulness of memoization is lower.
