That's a good question. I've given some thought to how we might build drivers in languages that don't support lambda functions and unfortunately, there don't seem to be any good answers. The actual underlying S-expression syntax for ReQL lambda functions is pretty ugly by itself and I'm glad that so far we haven't had to expose it. The python `lambda x,y: x + y` actually gets compiled to something like the following: `(func [1,2] (add (var 1) (var 2)))`. Variable references have to be constructed manually no matter how you do it. With native lambda functions though you can at least hide those constructions behind the scenes and bind them to the function's formal arguments. Fortunately though both C++ and Java, the two "traditional" languages we would most like to support, have either just (in C++11) or are about to (in Java 8) introduce lambda functions rendering the point moot.
