The intended error here is "cannot marshal value that is embedded in
compiled code" at `raco make` time, because fxvectors are not supported
as literals. I'll fix the bytecode writer to check for this case.
Meanwhile, the fact that non-literal values can be coerced to syntax
(as long as they don't have to be marshaled) is troublesome, but it's
useful enough in interactive situations that we haven't yet committed
to closing the loophole.
