Sorry for the less than informative title :). Lots going on here. It started as an attempt to fix unification to deal with laziness coercions in trickier places, but unearthed a couple of tricky and interconnected issues that are hard to unpick into a single patch. So, this fixes a few things: - default hints should only be resolved on the current elaboration (e.g. nested function definitions, not the outer definition which might not yet be complete) - delayed elaborators should be allowed to have nested delayed elaborators, which means disambiguation is a little bit better - we should delay elaborating arguments where the type isn't known yet, because later arguments may resolve the type, and we can use this to help with disambiguation/laziness coercions - other bits and pieces arising
