Declaring at the top of a function conflicts with the C++ convention of powerful constructors. It's perfectly normal for a C++ class to allocate a lot of memory, open a network socket, or do any other number of heavy-weight things during construction. If you declare all variables at the top of the function, you're forced to have C-style init functions for all data structures that you call separately.
