How to discover all package types at runtime?

Question

As far as I\'m aware (see here, and here) there is no type discovery mechanism in the reflect package, which expects that you already have an instance of the type or value y

Thanks @thwd and @icio, follow your direction it still worked on 1.13.6 today.

Follow your way the tl.s will be:

TEXT ·typelinks(SB), $0-0
    JMP reflect·typelinks(SB)

yes, no package name and no "add" function in it.

then follow @icio's way change "add" function to:

func add(p unsafe.Pointer, x uintptr, whySafe string) unsafe.Pointer {
    return unsafe.Pointer(uintptr(p) + x)
}

then all worked now. :)
