It's not quite that AST insertion is slow. It's the fact that you
have to do semantic processing piece by piece, which is expensive.
If you have completely semantically processed nodes, linking them
into the tree is quite painless.

What exactly do you mean.
type functions are a relatively simple extension of ctfe.

"..." is a little more involved but also not massively 
both should stay under 1000 lines when implemented
*fingers crossed*
