A good third language?

Okay, my main two languages are Ruby and C++. Although I've learned Ada out of school and I'm learning Scheme in school now, I don't consider them languages I'm generally GOOD with. So I'm wondering what third language I could learn to balance myself out.

a)You inherit the bugs in C++.

b)If a different programmer uses a different subset of C++, you're pretty much fucked when it comes to the build phase.

c)Templates aren't that reliable.
