> Descent has a problem: it supports D1 very well (kinda) but good D2 support is still far away.  The latest dmd versions I ported it to are 1.045 and 2.030. Porting from 1.045 to 1.050 should be fast (not many front-end changes). Porting from 2.030 to 2.035 is heavy because a lot of changes were introduced.

> In both cases porting is a slow (and boring) task: checking the diffs between each file, finding the matching function if it already exists or creating it, copying the code, translating it to Java, then translating some bits of code to Descent (it's a bit more than just copy, past, change size_t to int, remove stars). Doing it alone is really, really slow and boring, but I have no problem doing it from time to time, like maybe 10, 15 minutes each day.

Maybe some changes that were applied in 2.035 were roll backed or changed a little, so perhaps I should wait for D2 to become frozen and then port. Either way, I'm afraid that when I'll finally have good D2 support there will be a D3 in the way. When I stabilize Descent more or less (write a lot of tests, improve memory and performance, etc.) maybe the situation that exists now will repeat itself: D2 will be more or less stable but some people will be focused on D3 because it's the new thing, Descent won't support D3 because it's a moving target and because it's not backward compatible with D2, so I'll start porting to D3 but D4 will appear, etc.
