New submission from Batuhan Taskaya <batuhanosmantask...@gmail.com>:
This is actually a problem that is existing for a long time. A recent example
would be the discussion in the GH-19868.
Implementation
- It should check existence of all fields (like ast.Constant() wont verified)
- It should check types of all fields against their declarations in ASDL (this
is actually depending on GH-19031) (like ast.List({ast.Constant(1)},
ctx=ast.Load()) wont pass, or the example in GH-19868)
After bpo-39981 resolved, I'll submit a patch.
