rename eval to EVAL to indicate specialness
EVAL must have a special relationship with the compiler, so don't
pretend it's a normal function/method. We aren't capitalizing it
because it's a "come from" as most phasers are, but because it's
an escape hatch macro that is mostly there to compensate for an
insufficiently imaginative language designer.
