Comments like this make me nervous. :) 

How much of the stdlib do you think needs replacement? Which if any
modules should be considered stable? Can D2 users expect that the
stdlib in a year's time will look anything like it does now? Is there
a formal development plan?

I appreciate that D2 and its Phobos are works in progress. But I would
hope that a statement like "std.stream needs replacement," coming from
a core developer, would be followed up with either a replacement plan
or a rationale and a call-to-arms. Noblesse oblige!

Perhaps the D2 stdlib documentation should remind prominently that the
stdlib isn't actually standardized yet, and that it should be treated
as an experimental library.

Best,
Graham
