I got curious, think I found a way to get closer to the macro. Only does element contruction no attributes are set except id/className but that happens later anyways.
Uses element.cloneNode https://gist.github.com/thheller/7faf1c28ca14c9865376 See the related js-perf (not by me) http://jsperf.com/clonenode-vs-createelement-performance/32 I reused your parse-keyword function but wrapped into a memoize (well not memoize, but as low level as possible) and did a little benchmark. PARSE: 782.984ms CLONE: 141.103ms Looked nice, altough I did only test Chrome on my Mac. Results probably vary on every system but looks like a 4-5x speedup.
