Even though we occassionally talk about Lua on HN, it frankly still doesn't get enough attention - nor does Mike Pall and his fantastic work on LuaJIT.

Please considering sponsoring [1] LuaJIT so that Mike can continue working on it.

Lua Fun looks like a wonderful addition to the Lua ecosystem.

I wish that Lua get more attention.

> Reference Lua may not work and is not supported

Any particular reason for that?

Underscore Lua is a lib I have been using for quite a while.

Is this similar to the functools package in Python? If so, that would certainly convince me to use Lua for some of what I use Python for.

I can't agree with you enough.

You should use it for all of what you use Python for. Python is a sinking language, that has taken too much input from a community of bikeshedders, to the point it can barely move. LuaJIT makes PyPy look like a high school technology project.

In case you skipped the article it contains this nugget:

Take this example containing functional composition and higher-order functions:

reduce(operator.add, 0, map(function(x) return x^2 end, range(n)))

LUA converts this into 10 lines of assembler (2 jumps). Also, the LUA compiler is directly generating SSE.

Anyone have any good benchmarks comparing simple functional examples in LUA with Clojure or Common Lisp?
