I'm more than a little distrubed by this.  Consider...

  perl -wle 'sub foo { last; } while(1) { foo() }'

In any sane universe, that loop would never exit.  In perl's, it exits
on the first iteration (with a warning).  

You shouldn't be able to use loop control functions (last, redo,
etc...) outside a loop's lexical context.  Action at a distance at its
finest.

So I'd say tied variables are doing the *right* thing (although
probably for the wrong reasons) and tied($foo)->STORE($foo + 1); is
doing the wrong thing.
