That's what I'm trying to avoid. But I may have no alternative to do it as I
need this functionality for a new Logtalk port profiler (a performance analysis
tool). The format/2 predicate only provide the necessary functionality in 5 out
of 11 backend Prolog compilers supported by Logtalk.
Thanks for your feedback. Cheers,
Paulo
