I agree with you Greg about {}. +1

There is also a factor of underlying consistency in grouping that I 
like.  In most every place else in python a subgroup is delimited by 
like or opposing symbols.  So this just seems to be an extension of that.

Most of the examples have been reasonably easy to read because they 
contain white space at the right places.  To better compare use harder 
to read examples without white spaces.

     "abc%sefg"
     "abc$(s)efg"
     "abc{s}efg"   <-- I think this is an improvement.
