I have three logging functions that are almost identical.

If I move the identicle code into a function without pointers then there is a
noticeable speed decrease. I know this is premature optimisation as logging
shouldn't happen frequently enough or be that large (hopefully).

That said. I am left wondering aside from code generation steps and copy and
paste (current solution) if I am unaware of any options that might avoid pointer
use, such as:

1./ scoped global, like a Class might provide

2./ macro type instantiation that simply inserts the code at compile time but
without the compiler doing any computations

I assume not, from perusing the spec?

p.s. It's fine if the solution is pointers. Just wondering if I can avoid panic
potential.
