std.concurrency.Generator yieldAll?

[bearophile via Digitalmars-d]

Another problems of std.concurrency.Generator is that currently 
it's not pure, not nothrow, not @safe and not @nogc. So its usage 
turns clean code into something that much less guarantees. This 
is unfortunate because you want to use it mostly in the 
functional-style code where you want those well-behaving 
guarantees.
