            Bug ID: 61617
           Summary: add boost::coroutine
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P3
         Component: libstdc++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: piotr5 at netscape dot net

this has been suggested for addition in the next standard. it is an important
element of c++ because iterator-code can become quite incomprehensible
otherwise. but the main reason I'd like to see it as part of gcc is so that
programmers responsible for optimizations could start thinking up ways to
implement coroutines on the various platforms in creative ways. no need to wait
with optimization-ideas for the standard to include it, when it's already being
used in other programming languages. but if it isn't being used in c++ it
likely wont get much attention...
