Core async is also an example of a very powerful macro that rewrites execution flow; but they do decidedly different things. While Core Async is about powerful non-threaded coordination of processes, Javelin is about creating self-updating non-cyclical function graphs. Basically it's about automatically keeping a derived a view from a small set of data up to date when the source data changes. It's the exact same thing a spreadsheet does for numbers, but becomes much more interesting when the derived view is a DOM tree derived from database+view state. FWIW; I was inspired by the the work of Kenny Tilton (a.k.a. Smuglispweeny) and his Cells library and manifesto [1]. His work seems to be falling in disarray, but there's still some stuff up on the wayback machine [2][3] [1] http://smuglispweeny.blogspot.nl/2008/02/cells-manifesto.html http://smuglispweeny.blogspot.nl/2008/02/cells-manifesto.htm...
