In C would I just make a struct with fields of t_symbol,

Yeah, a linked list would work fine, probably not as efficient as the c++ hash
structure (but lots easier to maintain). One nit-to-pick: Use a t_class
pointer, which is a t_pd.
Hm... since the code to add new classes to the list will probably
end up looking exactly like the code to add symbols to the
symbol table, what if I just bloat the _symbol struct by adding
a t_class *s_class? Would that affect performance?
it would break binary compatibility.
there's no good reason to add hash-like lookups to t_symbol (your only
reason is convenience).
true, there's an s_thing there, but that's mainly for performance
reasons (looking up symbol->class mappings is usually outside a
performance critical path)(and having s_thing in t_symbol is very ugly)
Then searching for an existing class would be easy-- just do
a gensym and check if its s_class exists.
but checking whether a class exists, is as simple as calling zgetfn on
pd_objectmaker.
i think this is _quite_ easy.
