Some people might be quite excited by Milan's work on significant performance improvements to the containers package...
Ah. This all looks excellent! Currently jhc spends about 30-40% of its time in the containers package according to profiling so improvements there will notably speed up compilation. Though, I already modifed a lot to use IntSets instead of Sets and independently discovered the HashSet/HashMap trick, but the gain should still be signifigant. The focus on tree-union is particularly cool, as I know a lot of that goes on inside the compiler. John -- John Meacham - ⑆repetae.net⑆john⑈ - http://notanumber.net/
