Make executable archive just like Java's .jar archive?

A JAR file is just a standard zip file. The Java Virtual Machine
loads .class files (which are Java bytecode files, not Java
source) and executes them at runtime. It doesn't matter if
they're in a jar file or not. Java was designed for this from the
If you're really talking about loading .d *source* files, that
means they either have to be interpreted like a scripting
language, in which case you'll need a D interpreter, or they'll
need to be compiled at runtime into bytecode (in which case
you'll need a bytecode interpreter), or compiled at runtime into
object files, in which case you'll need a mechanism for loading
object files into a program (there was an object loader library
around back in the D1 days).
If you want to do what Java does and compile ahead of time to a
bytecode format and distribute the bytecode in an archive to be
loaded at runtime, then that requires implementing a bytecode
compiler, a loader, and a bytecode interpreter.
I know that LLVM can output bytecode, so with LDC that's the
first step out of the way. Now all you need is for someone to
implement a loader and bytecode interpreter.
