This patch turns parser.exprs into a list of QAPIExpression instead, and adjusts expr.py to match. This allows the types we specify in parser.py to be "remembered" all the way through expr.py and into schema.py. Several assertions around packing and unpacking this data can be removed as a result. NB: This necessitates a change of typing for check_if() and check_keys(), because mypy does not believe UserDict[str, object] ⊆ Dict[str, object]. It will, however, accept Mapping or MutableMapping. In this case, the immutable form is preferred as an input parameter because we don't actually mutate the input. Without this change, we will observe: qapi/expr.py:631: error: Argument 1 to "check_keys" has incompatible type "QAPIExpression"; expected "Dict[str, object]" NB2: Python 3.6 has an oversight for typing UserDict that makes it impossible to type for both runtime and analysis time. The problem is described in detail at https://github.com/python/typing/issues/60 - this workaround can be safely removed when 3.7 is our minimum version.
