[Python-Dev] Can we please have a better dict interpolation syntax?

What if lid1 is a float which you want to display with two digits past the
decimal point?

I think we've been around the block on this one a few times.  While %{foo}
might be a convenient shorthand for %(foo)s, I don't think it saves enough
space (one character) or stands out that much more ("{...}" instead of
"(...)s") to make the addition worthwhile.  In addition, you'd have to
retain the current construct in cases where something other than simple
string interpolation was required, in which case you also have the problem
of having two almost identical ways to do dictionary interpolation.
