Fantastic.

Hmm, one point against prefixing the algebraic expressions is that they
would be more likely to be used by themselves in an inline code block.
Maybe there is a better way to recognize when a line is a stack vs. an
algebraic expression. For example if the line is resolvable to a stack
operation (i.e. an element of '(+ - ...)) then treat it as such,
otherwise just treat it as an algebraic expression.

Yes, I need to learn calc as well.
