For me, the problem with that proposal is not the precise format syntax,
but the fact that formatting is tied to a specific function which _also_
outputs stuff to screen.
There are really use cases where you want formatting without using a
"print" function in conjunction. Web pages, sending notification
e-mails, changing labels in GUI apps... anything that talks to the user
in a different way than using stdout.
IMO, printing and formatting must be distinct (*). And formatting should
be convenient and i18n-friendly (i18n is more and more important in
(*) they should be treated separately in the discussion, anyway
