I was thinking to rewrite the C++ front-end not to use extra tree
codes you would also need to rewrite the C front-end but now thinking
about, you could use one tree code for all of C++ and then use
subcodes or at least one tree code for types, one for expressions, one
for decls and one for all others and then use subcodes.
This was part of the point of making decl nodes a hierarchy, to enable
exactly this (even though it has not been split into subcodes yet)
tree_contains_struct then allows you to exactly check things are still
safe to access.
