Description

An assignment like

auto [x, y] = std::tuple<int, int>{23, 27};

merely results in an empty block in the AST:

summary: io.shiftleft.codepropertygraph.generated.nodes.Block[label=BLOCK; id=1000106]
id: 1000106
label: BLOCK
propertyKeys: [DYNAMIC_TYPE_HINT_FULL_NAME, INTERNAL_FLAGS, TYPE_FULL_NAME, COLUMN_NUMBER, ARGUMENT_INDEX, ORDER, DEPTH_FIRST_ORDER, CODE, LINE_NUMBER]
propertyMap: {ORDER=1, ARGUMENT_INDEX=1, CODE=, COLUMN_NUMBER=36, TYPE_FULL_NAME=void, LINE_NUMBER=7, DYNAMIC_TYPE_HINT_FULL_NAME=List()}

No variable names, no types, no tuple, no assignments, no 23, and no 27.

Research direction

Reproduce the reported auto [x, y] = std::tuple<int, int>{23, 27}; example and inspect how tuple variable assignments are represented in the AST. Done means the AST preserves the variable names, types, tuple, assignments, and initializer values instead of producing an empty block.
