I'm not proposing a new API, but I'm not against it either.  What 
I'm proposing is to just copy over the existing APIs in Phobos 
that don't require druntime for their implementation.  It would 
probably be a good idea to exclude any API from Phobos that is 
considered a mistake. And, of course, some Phobos implementations 
do require druntime and dynamic memory allocation, so those would 
also be excluded, but everything else (that makes sense) could be 
copied over to the library I'm proposing.  Those familiar with 
Phobos would feel right at home using this library.
