This enables only inference for name binding in a *with* statement.
For instance, in the following code, inferring `func` will return
the `ContextManager` class, not whatever ``__enter__`` returns.
We are doing this intentionally, because we consider that the context
manager result is whatever __enter__ returns and what it is binded
using the ``as`` keyword.
class ContextManager(object):
def __enter__(self):
return 42
with ContextManager() as f:
pass
# ContextManager().infer() will return ContextManager
# f.infer() will return 42.
Arguments:
self: nodes.With
node: The target of the assignment, `as (a, b)` in `with foo as (a, b)`.
context: Inference context used for caching already inferred objects
assign_path:
A list of indices, where each index specifies what item to fetch from
the inference results.
