On the Windows team at Microsoft where I work, we work around the lack of actual named parameters by putting parameter names in C-style comments. To illustrate, given a hypothetical list class with a sort method like Python's, with a boolean "reverse" parameter, we'd call that method like this:
list.sort(true /* reverse */);
This convention is very handy for certain Win32 functions that take lots ofparameters, such as CreateProcess or CreateWindowEx.
