|What about using parameter passing semantics:
|
|  rescue FriendlyException(friendly)

In currnt syntax rules, rescue clause takes list of arbtrary
expressions which return exception object, so that
`FriendlyException(friendly)' cannot be distinguished from
invocation of the method named `FriendlyException'.

Some proposed 

  rescue FriendlyException do |friendly|

But I think it looks like blocks too much, since rescue works
differently from blocks.
