Interestingly, one of the developers on the Lua mailing list uses Lua in part because he is functionally blind, and the pronunciation of Lua code is unusually human-friendly. This makes both voice synthesis and dictation easier. There have actually been changes to several Lua projects to make the code itself more accessible to the blind, instead of just the end application.
That's interesting to think about: how would language optimization be different if we spoke instead of typed?
