Context

Support for dict attribute is a little inconsistent in Dynamo. There are three distinct implementations (see table below) and each one has its own problems. This PR introduces a new variable tracker ( DunderDictVariable ) which behaves as a regular Dynamo dictionary (subclasses ConstDictVariable ) and uses the side effects table as storage (dict.items = side effects table) Component Implementation Approach Issues / Benefits UserDefinedObjectVariable Stores mutations in self.attrsdirectlymodifedondict Tracks attributes modified directly via dict (e.g., obj.dict["key"] = value ). Synchronization burden with side effects; not the authoritative source. MutableMappingVariable Returns a new ConstDictVariable on every vargetattr("dict") call Creates self.genericdictvt from self.value.dict on demand. Critical flaw: Recreates wrapped dict on each access, breaking mutation tracking identity. Updates to the returned dict are lost on next access. GetAttrVariable Intercepts dict accesses with special callmethod handling Routes dictionary operations ( getitem , setitem , contains ) to obj.methodsetattrstandard() and side effects. Works correctly but limited scope - handles specific operations…
