Can't coerce UNKNOWN to string in substitution iterator at ./coerce.pl line 11,
        <> line 12 (#1)
    (F) Certain types of SVs, in particular real symbol table entries
    (typeglobs), can't be forced to stop being what they are.  So you can't
    say things like:

        *foo += 1;

    You CAN say

        $foo = *foo;
        $foo += 1;

    but then $foo no longer contains a glob.
