Re: new thought experiment: what would you add to Lua ?

[Frank Kastenholz <fkastenholz@...>]

First, it seems to me that Lua is really complete - I can do anything/everything I want.  So i don’t see anything as missing (in the sense of “I can not write a program to do X because Lua just doesn’t do Y”

That said, there are a lot of things that could be done as conveniences to the programmer, maybe making the code more concise, cleaner, easier to read, etc. several have been mentioned. 

One that i would like is a more concise way to append to a list.  Instead of “list[#list+1]=...” how about something like “list[++]=...”? 

os.setenv, as a counterpart to os.getenv?

I like the idea that someone else posted about a preprocessor

I also like the idea of a switch statement (maybe taking bash’s notion of patterns in the cases :-)

But none really are critical (to me)

Thanks
