The virtual machine can handle the first four local variables more efficiently than any local variable declared after that (see lload and lload_ instructions). So caching the result of the (inlined) getter may actually hurt your performance.

Of course on their own either performance influence is almost negligible so if you want to optimize your code make sure that you are really tackling an actual bottleneck!
