I wasn't really decided about that one. Since it wants O_symbol, there
no strong need to try to evaluate the expression (this is only needed
for seeing whether a complex expression actually can be evaluated to
O_constant or O_register). Changing it might catch some wrong uses early
(O_symbol which in fact can be resolved to O_constant or O_register),
but I'm certain these wrong uses can get caught later and not all wrong
cases would be caught here, so not changing the call seems to result in
more consistent behavior.

Thanks for noticing.
