Haven't really thought about that. Nesting is a big 
issue if in the embedded expression, there is another 
dynamic string expression. For example (the first
'%' immediately preceding the first quote denotes
the start of a dynamic string expression)::

>>> first_name, family_name = "Peter", "Johns"
>>> %"Hi $ first_name+%", $family_name$" $!"

'Hi Peter, Johns!'

However, nesting is really cluttering things up and
we should forbid it without loosing power:
The above example can be done without nesting:
>>> >>> %"Hi $ first_name$, $family_name$!"
'Hi Peter, Johns!'

Can you offer an example where nesting is 
better or necessary?

Cheers,
Yingjie
