Previously
respond_to?
assumed it was given a symbol argument, so it directly checked for that argument in the fields, which are force-keyed as symbols. If you passed it a string argument, it wouldn't find the corresponding field, impying it didn't respond to such a method.Now, the argument is explicitly cast to a symbol before checking if such a field exists, supporting checking
respond_to?
with both argument types.
