//     pointers and variables use "unknown_var" and "unknown_own" qualifiers.
//   - names don't use namespaces (by default)
//   - ifdefs etc. could be handled by cpp
//   - "#define C V" is replaced with "alias T C = V" if T can be deduced.
//   - "#define M(X) EXPR" is replaced with "alias TR M(TX X) { return EXPR; }"
//     if TR and TX can be detected.
//   - Use "cpp -dD" to include both #defines and the processed output
