Took a quick look at Tangent tonight, managed to not do much more than open 6 bug reports. Good to keep such things documented, bad that I've been so scattershot in getting things done. I happened across a nice list
of beginner style exercises. I think that will be a good reference for example Tangent code and stuff to work through to ensure everything is there and working.
Work is quieting down a little, so time should likely return for hobby work.
