Pre-increment non-primitive types.

Found with cppcheck:
"Prefix ++/-- operators should be preferred for non-primitive
types. Pre-increment/decrement can be more efficient than
post-increment/decrement. Post-increment/decrement usually
involves keeping a copy of the previous value around and adds
a little extra code."
