Using your very rigid definition of "platform agnostic", you can't do
anything in a platform agnostic way, not even add two and two. Using a
*useful* definition of "platform agnostic" -- say "runs on anything that
has an ANSI-compliant C compiler for it" or "runs on anything that has a
JLS-compliant JVM for it" -- it could conceivably be another story.

Hexapodia is the key insight.
