"foo %s bar %s, %s, %s, %s, %s" % (foo, bar, map(lambda x: baz(x), [1, 2, 3, 4]))
You could use list concatenation (+) to do something like
"foo %s bar %s, %s, %s, %s, %s" % tuple([foo, bar] + map(lambda x: baz(x), [1, 2, 3, 4]))
... which is slightly uglified by the "%" operator not accepting a list (hence the "tuple" call). But yeah, it would be handy to be able to use the argument list syntax in other places.
Still, 15 lines? :-)
