I assume the numbering (1,2,3,...) is anchored in the program logic (that is, they are related to fixed points in the computation), not in memory conumption of something like that. If that is true, w

Hmm. Okay, first I want to say that I really appreciate you going through all the effort to bootstrap this comparison. I think we may have a misunderstanding though -- my objective was mostly to save

What exactly do you mean with this: When I read about the plan to remove the __ipairs metamethod in Lua 5.3, I got doubts whether my approach to use ipairs(...) for iteration is semantically correct.

It was thus said that the Great William Ahern once stated: I do, so that's not ANSI-C. It's POSIX. I also think that if a feature is so damn hard to use, perhaps it's time to retire (with extreme pre

I couldn't reproduce exactly, but I have an idea what it might have been. Could you try again? This is a little ambiguous as there are two cases: * calling an instance method on the class * calling a

It is my point. The Lua 5.3 manual states: "Standard Lua uses *64-bit integers* and double-precision floats, but it is easy to compile Lua so that it uses 32-bit integers and single-precision floats.

Below you've written a nicer rundown that takes in account common syscall-reducing optimizations. It's easy to see that malloc behavior potentially varies to a greater degree than architecture vm spe

Because the signedness of integers in C is part of their type. You snipped the rest of the code; I'll paste the end: The point of this is not just to build a debug aid like print() but also to suppor

Fascinating. 2013-04 Apple clang on 10.7 doesn't seem to have the problem. (Yes, I scratch-installed a box to check the situation out. I'm not sure what that says about me.) $ cc -v -m32 Apple LLVM v

Heap randomization is a security feature to some degree, and so is non-deterministic hashing (which most Lua implementations don't provide, alas). No, these are fully deterministic. It may be benefi
