For m_symbolarray the main reason was speed and as a side-effect allowing
"holes" in the array. Accessing an array (even one in a data structure) is a
lot faster than sending around a long list every time a lookup is needed.
m_symbolarray made a patch run nicely on an iPhone that was totally
overloading the device before. 

Of course often you just can get away with the usual approach that you outlined
above, and please do so, if you don't run into problems.

But if a) the number of names (i.e. the list length) gets large or b) you have
to activate this idiom many, many times, you can hit a wall. And it's quite
easy to make a) and b) with sample players if you play polyphonic music with
many instruments in it. Here m_symbolarray is one way out.
