I would prefer that the case of ~X matches the case of the hex characters, but can't specify more than R5RS here. Note that the reference implementation maes use of NUMBER->STRING. > Also, the spec says it is an error to pass fewer arguments than > needed, but is it ok to pass more arguments? I consider it useful to detect this as an error, but there are other sensible ideas. E.g. one possible return value for FORMAT is the list of unused arguments. I prefer that FORMAT invoke ERROR rather than failing and returning #F, as SLIB specifies. However, I prefer to leave FORMAT's return value unspecified in srfi-48 and come to concensus on an advanced format srfi. Cheers, -KenD
