Comments in code

[shewitt-au]

Please, for God's sake, comment your code! This is complicated stuff. Especially for newcomers. Comments can be just as important, in some cases more important, than the code itself. Good comments are an integral component of good coding. Sorry to bitch (and preach), but while I'm at it, lay off the lambda functions. A stack trace tells a story. Too many non-trivial lambda functions muddle the narrative. I’m not trying to be confrontational here. Just my honest impressions as someone who has done a lot of debugging but is new to this code base, and is trying to contribute.
