It is fairly unperlish to have large blocks of variable declarations at
the top of a subroutine so throw away variables (like a one used only
within a loop) tend to get declared as they are used. The only reason I
can think of that would make it faster is that declaring $i this way
tells the compiler that $i is not going to be permanently stored, so it
may stay in a register.
