@unnamed1337 Thanks for the contribution! I am currently preoccupied with other projects ATM but when I get back around to this (and I do plan to, I have other stuff to add), I'll merge the your addition.

However, I will not merge the change in braces style though. I know it comes down to personal preference, but it's standard practice that you follow the coding style of the existing project. Otherwise it introduces diff noise (noise between functional and cosmetic code changes) and inconsistency and maintenance pain. EG: dev A prefers one style and dev B prefers another, they will both be changing the style each time they want to add a feature. Then say dev C comes along and adjust the style that's also different both A and B. Chaos!

This is not to say your brace style is wrong. If you change it back to the original (no new line on opening brace), it will make the merge easier for me.
