Can you folks comment on what you see as the the transition plan?  The 
migration document does a decent job explaining how to convert from 
Phobos over to Tango whole hog, but realistically not everyone can make 
this transition overnight.  So anyone writing libraries intended for 
consumption by 3rd parties is faced with the options of
A) Port whole hog -- abandoning any users who are stuck with Phobos
B) Don't port at all -- annoying any users hoping to move to Tango
C) Port while maintaining compatibility -- annoying the poor me who has 
to deal with incompatibilities in the most basic functions (e.g. 
toString, writefln)


Option C) seems like the most logical.  And given that, it seems like a 
compatibility library would be helpful.  Some way to make it easier to 
write code that looks mostly like Tango code with a minimum of version 
statements, but which actually calls on Phobos at the bottom layers.

Or maybe I've misunderstood the options.  Given the new GC and new 
Object class it seems like any use of Tango with Phobos is radioactive 
and fraught with peril, but maybe its not so bad?  For example, can one 
use the io framework from Tango while still using Phobos as the std lib?

Anyway, I think a page on how to migrate from Phobos to Tango while 
mainintaining backwards compatibility would be of great use to library 
writers.
