Well, like I said, it's too late at this point, and really, it would be good to have a nice way to deal with C functions and purity (particularly since most of them are pure anyway), but the result at present is that most functions should be marked with pure. And if you're marking more functions with pure than not, that would imply that the default should be (at least ideally) impure. Regardless, however, it's not reasonable for D to go for impure rather than pure at this point. - Jonathan M Davis
