BZZT! Wrong, but thank you for playing. :)

The actual *hardware* may present a Harvard architecture, but if the program
that's running is an interpreter, *that* can (if it so chooses) present a
Von Neumann architecture to the interpreted program (because to *it*, both
the interpreted program and the interpreted program's data are *bot* just
data to the interpreter).

Hint:  Most modern microprocessors are essentially a Harvard architecture
under the hood - but they have no problems looking very Von Neumann-y to
the operating system... :)
