It's a shame that Julia does Perl-style nested array flattening: http://t.co/A3HOhjZR01

On storing ASTs in flat arrays for performance, and the relationship with bytecode interpreters:

Flattening ASTs (and Other Compiler Data Structures)

This is an introduction to data structure flattening, a special case of arena allocation that is a good fit for programming language implementations. We build a simple interpreter twice, the normal way and the flat way, and show that some fairly mechanical code changes can give you a 2.4× speedup.

Emacs command of the day: lispy-oneline, bound to O in lispy-mode. Great for flattening small expressions:

lispy.el function reference
