The discussion about RFC 227 in -internals brought up a few good ideas about a taint pragma. In brief: - taint(), tainted() and other such functions would be useful when sending scalars around or inspecting them. A few other functions may fall into this category. - untaint() should not be one of them - this pragma should be shipped in-core, so that there are no issues with C-compiler requirements (see Dan/TomP's Taint modules). - this is not about lexical tainting, which is a *BAD* idea - this is not about taint() and untaint() filehandle methods, which are happening anyway. All that said, does 'use taint;' make sense? The good idea that Bart brought up with 'use memoize;' still applies. Specifically that a :tainted sub attribute (and param attribute?) may be useful, but that is not within the realm of -stdlib. Z.
