The most likely implementation is a check that varslist must be {} if 
body is "-".
e.g.  try { ... } on break {} - on continue {em opts} { ...handler for 
break and continue, gets em+opts... }

I could allow varslist to be {} or "-" in such a case -- it's prettier, 
but "-" is in fact a valid varslist (assigns the result to the local 
variable "-").
e.g. try { ... } on break - - on continue {em opts} { ...handler for 
break and continue, gets em+opts... }

I'm hoping to put the Tcl implementation into tcllib (possible in the 
control package), giving [try] functionality to Tcl 8.5.  This will then 
be an appropriate place to experiment with new features (like 'as').  
 From there I imagine they may be TIPped into the core.
