Packfiles need to have a symbol table. A series of name/type/location tuples so we can have global names that map to values in the bytecode, either variables or subroutines. When the bytecode is loaded, we need to put those symbols in the symbol table and construct the backing PMCs.
Guess what you really want is a symbol table (with name/type) and a rellocation table (symbol number/location), to avoid having the name repeated, right?
Yup. I don't think a whole lot will end up using the relocation table, but no sense in having two separate ones, since that just means more possibility for things to get out of sync.
