True, and as a rule I use a sequence of statements when the formatting
is a series of logic steps (i.e. an algorithm). But for simple string
building this is verbose, and more fundamentally, it turns an
expression into statements. I think this is what creates the biggest
craving for an infix solution; not necessarily terseness, although
that comes as a consequence of more elegance in expressions.

Aside: Statements do not compose. E.g. f (g ()) breaks apart and
introduces named types and tem****aries if f or g must be expressed as
statements; i.e. R r; f (r); g (r).

This is an expressive solution, but see my reply to Niels for a terser
and more efficient alternative.
