Some TeX Developments

Taking good practice from LaTeX3

LaTeX3 provides a well thought out low level programming environment. There is a lot the (La)TeX programmer can learn about good coding practice from the current experimental code, and I’m trying to use this in siunitx version 2. There are lots of little points that I could highlight, but I’ll pick a few out:

I’m also taking some of the other ideas in siunitx version 2. For example, where possible I’m aiming only to use \edef where it is really needed (unknown levels of expansion). If something needs to be expanded a known number of times, I’m going for controlled expansion instead. I’ve also really like the idea of switches that don’t use \iffalse and \iftrue to work: much less risk of problems.
