gollark: <@332271551481118732> Expression parsing is done, I think.
gollark: I wonder if AQA pseudocode *does* have operator precedence. We may need to harvest exam papers.
gollark: This will allow 3% more efficient harnessing of character set anomalies.
gollark: The parser supports anomalous unicode, muahaha.
