developer wants to construct elements more quickly.

[jumblerg]

potential optimizations include:

1. eliminating all remaining seqs from hoplon and ui.

2. adding a .-constant property to javelin cells that will indicate if they're guaranteed to be static, and check for the presence of this property before adding any watches.

3. splitting parse-args into a preparse-args macro that groups attributes into a map and children into a vector at compile time and a postparse-args fn that merges any remaining arguments that could not be resolved at compile time into the collections create by preparse-args.

4. prerendering out any terminal branches of the dom tree determined to be fully static at compile time into html strings and inserting them with `.-innerHTML.

5. investigating the use of caching and deep cloning of multiple elements in ctors, *-tpls, etc.
