I've occasionally wished that we could repurpose backticks for expression literals:

 expr = x + y*z  assert isinstance(expr, ast.Expression)

Maybe you could just as well make it a plain string literal and call a function that parses it into a parse tree:

expr = parse("x + y*z") assert isinstance(expr, ast.Expression)

The advantage of this approach is that you can define a different language too...
