 > Note: Because `++` and `--` always have in-place update semantics, we never need to remember "use prefix `++`/`--` unless you need a copy of the old value." If you do need a copy of the old value, just take the copy before calling `++`/`--`. When you write a copyable type that overloads `operator++` or `operator--`, cppfront generates also the copy-old-value overload of that function to support natural use of the type from Cpp1 code.
