Title: Renamed hasSymbol to hasSymbolField.

Suggestion by retronym that the obvious implementation of
"hasSymbol" be called "hasSymbol" reminded me we have a method
called "hasSymbol" which does not have that implementation, and
which has burned us already with subtle bugginess. I think that
"hasSymbolField" is self-documenting.
