The other difference is that my suggestion supports Barry's desire to use
string.Template with no muss, no fuss ;-) Plus, very little additional work is
required compared to your items 1 and 2. ISTM BraceMessage would be something
like this,
clsss BraceMessage:
def __init__(self, fmt, *args, **kwargs):
self.fmt = fmt
self.args = args
self.kwargs = kwargs
def __str__(self):
return self.fmt.format(*self.args, **self.kwargs)
