Hi folks,

Newbie question: if the D compiler (a) is very fast and (b) can
optimize application code when it has access to all library sources,
then isn't libphobos2.a a premature optimization? Why have it at all,
when the Phobos sources are available?

Thanks,
Graham

The global optimization at the moment is limited to inlining. Most functions
are 
not inlinable.

Don't you need the phobos source regardless of whether you have a lib file?

It's enough with D interface files/headers. Look at object.di and 
core.Thread.di(I think) for example.
