We wantlvalue(), too!

To be usable, the :lvalue attribute really needs two things added.

1) A function needs to be able to figure out whether it was called
   in an lvalue context of now.  Rather than (just) adding an umpteenth
   return to caller(), there should be a wantlvalue() built-in.  You cannot
   write something like 

2) You also need access to the right hand side, just like tie's STORE
   provides.
