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 :-)
You *do* have a named top scope, the module name (which is
accessible with prefixing a symbol with ., i.e., .x refers to the
symbol x at module scope). There is no such thing as global scope
in D.
