While this is often a good rule of thumb, occasionally it's useful to extract a function just to make the inputs clear for a complicated calculation. Particularly when it has few inputs and they are unlikely to change.

With modern C++ you could do this with a lambda

Which compiler that can compile modern C++ doesn't always inline a static single-caller function?

[Hydraulix989]

All of them? There's many cases where it doesn't make sense:

- The function is exported to a library

- The code generator emitted an indirect branch instruction

- The inlined code exceeds the size of a single page in memory

- The inlined code does not perform as well because it is not i-cacheable
