I'm starting to like MS' formatting approach where

format("{2} is {1:fmt}", x, y)

is translated into

to_string(y) + " is " + to_string(y, "fmt").

This combined with a default formatter that understands printf-like syntax
would look like

format("{2:10} is {1:6.3f}", "test", 0.5);

Naturally, the default formatter would be user-replaceable, enabling people
to add verbosity as desired.
