Took a few days off to encounter the weirdest of all bugs. I go down a directory, try the help option, it borgs; go one up, everything is fine. Still a memory error, I guess.
Got mostly rid of the stuttering. It identifies the system file, not very happy about the speed, which probably means my size-hardly-balanced maps are not very fast, trying to get it to compile the system file. Great, it catches small semantic bugs.
Runs like a charm at the moment, instead of debugging the output, I am debugging the input.
[ It crashed on outputting the compiled system file, which makes sense, since its own system file has bugs. Regenerating the bootstrap. ]
