Vala does have multiple inheritance, or at least I don't see how its mixins are fundamentally any different:
http://live.gnome.org/Vala/Tutorial#Interfaces_.2BAC8_Mixins
Vala has generics. I'm not sure what aspect of C++ templates you miss, but I sure don't miss the multiple-pages or more of incomprehensible error messages that are inherent to even minor mistakes with C++ templates. ;)
Vala is statically typed, not sure why you'd think otherwise (it allows type inference of LHS in assignments with "var x = y;" - a handy convenience, and still statically typed).

LLVM 3.0 released Posted Dec 12, 2011 10:11 UTC (Mon) by mpr22 (subscriber, #60784) [Link] As that page describes it, Vala allows you to inherit at most one class and any number of interfaces (and the page explicitly says that it's a restricted form of multiple inheritance). C++ allows you to inherit multiple concrete classes. (It happens to be the case that I've never encountered a case where I thought I had a reason to use this capability, but I am not every C++ programmer.)

So, it's perhaps a little hidden away in one sentence of the last paragraph of that interface/mixin section, but Vala interfaces may contain concrete implementations. I.e. Vala has multiple inheritance - the only difference in Vala is that the classes being inherited from must mark themselves as being comfortable with that (not a fundamental difference).
