When you already have a dict, the dict-based
formatting would be nice.

>>> "%(name)s works as %(job)s"%b

If it you need to create a dict just for string

formatting, dynamic string would be nice.
Say your object has methods/properties
that fetch things from your database.

>>> class staff:
...@property
...def name(): return 'Peter'
...
>>> t = staff()
>>> vars(t)
{}
>>> t.name
'Peter'
>>> d"Staff name: $t.name$" #note the d"..." format
'Staff name: Peter'

Because of the d"..." format, it won't 
affect old ways of doing things one bit.
Allowing dynamic string wouldn't hurt 
a bit to anything that is already there.
