I'd really hate to see opApply go away.  I'm glad Walter says it's sticking around ;)

opApply is really nice in how *simple* it is to write.  I think it's possible to use druntime's fibers to convert an opApply implementation into a range implementation.  It'd be an interesting challenge to write a templated struct that handles all of this.  Once that is done, maybe someone could discuss using Fibers to implement opApply in D2.  I suspect the code inside an opApply would only change a little bit and it'd allow iteration over multiple "ranges" at the same time.
