Yes, so if you cannot have the function pointer (like in func foo() {}; fp
:= foo) then there is nothing to compare so I don't understand what's the
connection to comparing of function pointers.

Addresses of function variables can be compared freely without any
limitation. Note: There's a distinction between the value of a function
variable (that's the function pointer) and the address of the variable,
that's not the function address and so it can be compared normally. To be
explicit. Address of a function variable is a pointer to a pointer. Maybe
that's making this thread confusing.
