I disagree, but then I don't understand how Robert would make C's
template idea type-safe -- might Robert expand on his ideas?

I think that the present method of concatenating strings or using
several Puts is good; what is needed is to extend or replace the 'Image
attribute with similar value-to-string functions which are more
controllable, flexible, and work also for composite types. Perhaps
something analogous to the stream attributes, but with the ability to
control the output format at each invocation, which is not possible with
the stream attributes.
