No, I wasn't suggesting removing bin_write() - in fact I think Martin
is already rolling it in to the runtime.

I was considering this as an optimization - if there are only binary
specifiers in the printf() statement, the translator might decide to
generate code to write the data into the buffer directly instead of
calling bin_write() to do it.
