A typedef question

[cup]

I only found out last week that this was possible

typedef int INTEGER, *PINTEGER, **PPINTEGER;

You can also add references to it

typedef int INTEGER, *PINTEGER, &RINTEGER;

What is strange is that you can do this

typedef int const *CPINTEGER, INTEGER;

but not this

typedef int INTEGER, const* CPINTEGER;

I would love to do

typedef list<int> IntList, ::iterator IntListIter;

Does anyone know of any other symbol other than * and & that can appear after the comma?
