A difference:
- it isn't possible to derive the address of a named variable from the
address of another named variable
- it is possible to derive the value of a named const from another named
const
const (
a = 0 // b-1, c-2
b = 1 // a+1, c-1
c = 2 // a+2, b+1
)
Reflection needs to be put aside because it can be made to access almost
anything we want.
