@tarcieri with #695 merged to signed-int, whats the plan for this feature? Specifically, will it be included in the next release? Could be helpful esp. because of comparability other crates like elliptic-curves depending on crypto-bigint

tarcieri commented 3 weeks ago

@ycscaly yeah, we should be able to get at least a preliminary implementation into the release and then we can additively improve it.

I went ahead and added it to the list in #681
