yes. all templated functions (and `someFunc()` is templated due to `S`
being templated) are subjects of attribute inference. due to this fact
people sometimes writing even free functions as argument-less templates,
void freeFunc() (...) { ... }
so compiler will infer attributes for `freeFunc()`. this has almost no
cost, as compiler will merge all produced templates into one.
