No way. Jarkko says that "transparency" (the fact that only the "logical representation" matters outside of XS) is no more a goal for Perl. I say that Perl which does not achieve transparency is useless Perl (in presence of high chars - but since you never may be sure, almost always). The choice of internal representation may matter performance-wise, but this may be addressed with pragmas. [BTW, if I correctly understood what Jarkko was insinuating, we have no choice now: if a string contains only logical chars <256, it is *forced* to bytes... I hope I'm wrong...] > Apart from pack's U & C this does not leak into the > "logical" world. And there is no reason for them to leak too. The operations they do have perfect sense in the logical world too. Currently I see no need whatsoever to have not-transparent operations *at all*. But if judged *needed*, they should be accessible from a module, to have the core "clean". IlyaThread Previous | Thread Next
