works for me (gcc 2.9 on BeOS R5). pre-increment/post-increment doesn't 
matter for a single statement, btw.

no, it doesn't get rid of the declaration (all variables have to be 
declared), but it makes it simpler to read and understand (and easier 
to type). also, it makes it easier to make changes: for example

typedef std::vector<Test *>::iterator TestIterator;

occurs exactly once. If you need to change the class type later, you 
can do so at that one spot rather than having to do a global search&
replace for every instance of "std::vector<Test *>::iterator" in the 
code.
