It feels like premature optimization - people should be allowed to
write slow code, and thereafter (if needed) optimize it; Lua 5.2 is
already optimizing closure creation.

Actually the 'make a field extractor for foo' is a good example of how
sometimes a little lambda is easier to write and read than a library
function.
