Why the Standard Library

[Sean Kelly]

The only thing actually required to build a D app is druntime, which contains threading support (needed so the GC knows how to scan threads spawned by the app), a GC, and compiler support code. When Phobos is built, druntime is bundled into it, so only Phobos is actually linked.
