pure functions are also supposed to don't use global variables at all, according to functional programming paradigm
Pure functions are immutables (constants but not "const" in the D or C++ senses) and can use other immutables, even if they're global immutables. (I guess it would be better though always to have a named top scope instead of everyone in the world having the same global scope :-)
