If I understand purity correctly
(http://klickverbot.at/blog/2012/05/purity-in-d/), every function out
there can be marked pure as long as it doesn't modify globals, shared
variables or do I/O?
Pure functions also can't *read* mutable globals. But then that's it,
I think.
Thanks. Now I'm excited to spam it over my codebase and see the kind
of speedup one can achieve.
I am not sure, but my guess is there will be no speed up :-).
