It is not used with a function literal but searching for 'alias' below 
yields something close: :)

Function pointer syntax is relatively harder to read; it is common to 
make code more readable by an alias:

alias CalculationFunc = int function(char, double);

That alias makes the code easier to read:

     CalculationFunc ptr = &myFunction;

As with any type, auto can be used as well:

     auto ptr = &myFunction;
</quote>

As others have already said, &myFunction can be replaced with a lambda. 
Shamefully without compiling:

     auto ptr = (char, double) => 42;
