This clearly shows, that packageName is only instatiated once at top

Now I don't know if this is a bug in DMD or I should know something I do
not know... Can you help me?

If you switch the last two lines around, you get "package foo" twice.
The compiler apparently thinks that m2 (module foo) and p (package foo)
are the same thing when used as a template argument. So it reuses the
previous result.
There's a similar issue with values:
