Semantic seems quite heavyweight, and is not that well documented. the
manul reads more as describing a box of parts, but doesn't really
provide much help in assembling them into something useful. It would
benefit from being split into a user guide and and an internals manual,
with some worked examples for both.

Broaden your thoughts: there are other languages beyond C. In some of
them (e.g. python, haskell) indentation is semantically significant.
