inline
makes sense in the header, along with the function definition. If it's in an implementation file, multiple definition isn't an issue, and the compiler will have a hard time inlining it anyway outside that translation unit (and inside that translation unit, it probably won't matter anyway - it's just a hint).
I guess, functionally, the answer is no. Semantically, inline doesn't make any sense in the cpp file.
