We already have one complex minilanguage inside {}, do we really want
another?
Maybe if we use regexps .... ;-) But seriously, if you want complex
conversions, you can just call a function in there, which gives you
arguments if you want them. Or in this context you can wrap the
object in a proxy with an appropriate __format__. This can be quite
generic, and allows you to put the arguments into the format spec.
