   How about @(x-1, x+1), with default args of x, y, and z? Otherwise
e.g. @([a,b] a-b, a+b) I may work on a patch for that over the
weekend.

   For anything larger, "function(x) return foo end" is fine, but
function/return/end adds a lot of noise in a big table full of very
short callbacks.

   Either way, I would strongly suggest to avoid using the word
"lambda". It's longer and less clear than several alternatives (e.g.
"fun"). Programmers familiar with the lambda calculus are really not
the majority, and it's pretty opaque to non-programmers just using Lua
as a config file format.
