An FP language doesn't preclude non-FP code, just like OOP doesn't preclude ... procedural code? I'm not sure what the opposite would be but it exists (think Matlab code). I would argue that the lisps are not very functional languages (both in the importance of effects and the style of code I've seen written in lisps), but Scala provides for a lot of FP assurances (val over var, good FP-y libs), and people in the community value effectlessness. So I'm comfortable calling Scala a FP language.
