What I really want to achieve with this is error-check the
version/debug identifiers that the program has been compiled
with..

e.g. if I compile the program a version-identifier with a typo:

dmd main.d -version=Inclde_FOO

then I want the program to be able to detect this by listing all
version-identifiers and checking them..
