I tried this branch, and I tried to make it pass all the tests. And it
did mostly work, except with tied variables.

I don't know what would be the proper solution for tied variables, but
I used this hack to make the tests pass:

--- a/Src/builtin.c
+++ b/Src/builtin.c

        tdp->joinchar = joinchar;
        tdp->arrptr = &altpm->u.arr;
+       altpm->node.flags &= ~PM_DECLAREDNULL;

        pm->gsu.s = &tiedarr_gsu;
        pm->u.data = tdp;
