*	4261 - start using literals for 'true' and 'false'	Kartik Agaram	2018-06-17	1	-4/+4
\| \| \| \| \| \| \| \| \|	They uncovered one bug: in edit/003-shortcuts.mu <scroll-down> was returning 0 for an address in one place where I thought it was returning 0 for a boolean. Now we've eliminated this bad interaction between tangling and punning literals.
*	4160 - named marks for delimited continuations	Kartik K. Agaram	2017-12-15	1	-5/+5
\| \| \| \| \|	Hypothesis: this is needed to build McCarthy's amb operator. https://rosettacode.org/wiki/Amb
*	4157	Kartik K. Agaram	2017-12-09	1	-2/+2
