Re: Attributes

Code is written for humans to be read and only incidently to be executed by a computer.

In my opinion if a language addition does serve neither the programmer nor the language execution performance it should be discarded.

That being said I've heard the <const> keyword does help for constant folding. If I want to write performant code I first try non idiomatic overhead free Lua code and second C code.
The const directive would probably serve little to no additional performance gain in the first case and none in the latter. Additionally you'll lose backwards compatibility, a tradeoff that doesn't make it worth for me to use this feature.

> The const keyword is an unambiguous directive for the compiler (or runtime VM) in 'your' dynamically typed language. The fact it serves as a hint for the programmer reading code, is a side-effect of the above and not its primary purpose.
