I tried repeatedly but unsuccessfully to wrap my mind around ptr to methods, until I hit P130 [[essential c++]].
Your class should have a bunch of sister methods with identical params and identical returns. Remember every ptr VARIABLE exists as (compile time) symbol table entry with
– a name,
– a value (address of the pointee) and
– a declared type
This pointer var can point to any of those sister methods, but not any look-alike methods in other classes.
 there’s no such thing as a “pointer” — only pointer _variables_ and pointee addresses.
