*	2929 - fix a bug in static dispatch	Kartik K. Agaram	2016-05-05	1	-11/+63
\| \| \| \| \| \|	Thanks Caleb for finding this. We'd been using sandboxes for so long, I hadn't tried a null/0 screen/console in a while and somewhere down the road Mu stopped matching 0 against concrete addresses.
*	2880	Kartik K. Agaram	2016-04-27	1	-1/+2
\| \| \| \| \| \| \| \| \| \| \|	Turns out we don't need a primitive to return an empty value of arbitrary type. Just create it on the heap using 'new'. But this uncovered yet another bug, sigh. When I specialize generic functions I was running all transforms on the generated functions after specialization completed. But there's one transform that includes code from elsewhere. If such code included type-ingredients -- kaboom. Now fixed and there's a test, so I've got that going for me which is nice.
*	2864 - replace all address:shared with just address	Kartik K. Agaram	2016-04-24	1	-4/+4
\| \| \| \| \| \| \|	Now that we no longer have non-shared addresses, we can just always track refcounts for all addresses. Phew!
*	2830 - bring back deleted test from 2829	Kartik K. Agaram	2016-04-10	1	-1/+19
\| \| \| \|	Issue 1 in 2829 is now fixed.
*	2829 - issues while switching to 'put'	Kartik K. Agaram	2016-04-10	1	-19/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	1. It turns out we couldn't overload 'get' and 'get-address' until now, because transform_names looks for those names, and the resolve_ambiguous_calls transform happens before transform_names. Why does resolve_ambiguous_calls happen before transform_names? Because if my students made mistakes in the ingredients to an instruction they got overzealous errors from resolve_ambiguous_calls. Now this impacts 'put' as well, which is already overloaded for tables. Not sure what to do about this; I'm going to go back to the overzealous errors, and just teach students to visually scan past them for now. 2. I need addresses in a third place besides storing to containers and arrays, and managing the heap -- to synchronize routines. wait-for-location requires an address. Not sure what to do about this..
*	2803	Kartik K. Agaram	2016-03-21	1	-3/+3
\| \| \| \| \|	Show more thorough information about instructions in the trace, but keep the original form in error messages.
*	2799 - new approach to undoing changes in tests	Kartik K. Agaram	2016-03-20	1	-7/+7
\| \| \| \| \| \| \| \|	As outlined at the end of 2797. This worked out surprisingly well. Now the snapshotting code touches fewer layers, and it's much better behaved, with less need for special-case logic, particularly inside run_interactive(). 30% slower, but should hopefully not cause any more bugs.
