Neat elisp feature I learnt today: because closures are just lists, you can manually construct them and call them as functions: (mapcar '(closure (t) (x) (1+ x)) '(1 2 3)) ;; => '(2 3 4)

I've just added closure support to my toy programming language: https://github.com/Wilfred/garden/commit/d1fb4566a2187dfe98fb1d2278a7a0d2acd8059e Closures are more fiddly than I expected, but I now have a much better understanding of what downward/upward funargs are :) (Downward: passing a closure, upward: returning a closure)
