It is probably a matter of personal taste, but i find it easier and 
cleaner to get the result of lookup_symbol (...) assigned to a variable 
and then have the code access its 'symbol' field as opposed to chaining 
things like the above.

The current codebase doesn't show many occurrences like the above.
