How would Valgrind help with Perl data structures?

As far as I'm aware, Valgrind can only check whether a C program overwrites memory it has not allocated, and maybe can check whether a C program allocates memory and then loses the pointer(s) to that piece of memory. If you have a valid Perl scalar, Perl will keep a valid (C) pointer to it, and will release the memory during Global Destruction. If that's true, then Valgrind will/can not flag this Perl value as ever lost, even though it may be a memory leak in the sense that there is no Perl structure from the running set of Perl variables to access that piece of memory.
