Is it ok to have macros that start with an underscore? I thought identifiers
starting with _ are reserved in c/c++, but not sure about macros.
Also, since this is a header file should we undef them at the end? Not sure we
expect others to use the macros themselves, but more of just an implementation
detail of the header.
