Right.

Java often runs on a JVM, so it keeps its compiler around at 
run-time, unlike most cases in D.

With enough work you can do the same in D with the LLVM, and keep 
the compiler as a service at run-time, if you want even as a JIT. 
But currently ldc2 doesn't have this feature.

Currently probably you can synthesize D source code, save the 
source, call the D compiler from D, and use it as library.
