It seems simple:

Cool, what if I want to use different versions in different sessions, i.e. I have two tabs open in my terminal?

More or less related: it would be nice if DVM supports LDC fetching and switching.
The use case I see is that you often want one DMD and one LDC.

Ummm...
All the installed stuff is pretty well organised inside `/usr/local`, so this works...

The advantage of DVM is that you don't have to modify any build scripts, makefiles or similar. Invoking just "dmd" in a build script will invoke whatever version the user has set for the current session.

Yeah, that would be nice. Would it be interesting to have "dmd" point to "ldmd2" when LDC is selected as the current compiler? Or is that just confusing.

Confusing. For me it's much more common to want a current DMD compiler and a current LDC compiler.

My idea was that this would allow to compile using LDC for a build script that was only designed with DMD in mind.

Of course the "ldc2" and "ldmd2" binaries would be available as well.
