Not so fast. If you make this a language feature you force all Python implementations to support an identical AST API. That's a big step.
I have been wondering about this. One could think from the manuals that we are there already. From the beginning of the ast chapter:
"The ast module helps Python applications to process trees of *the* Python abstract syntax grammar. ... An abstract syntax tree can be generated by passing ast.PyCF_ONLY_AST as a flag to the compile() built-in function" (emphasis on *the* added).
and the entry for compile(): "Compile the source into a code or AST object." I see nothing about ast possibly being CPython only.
