class sun::ast::CompoundAssignmentAST : public sun::ast::ExprAST

Compound assignment: target op= value (e.g.

x += 1, obj.f *= 2, arr[i] |= mask). Kept as a single node through analysis and lowered in codegen as address-once -> load -> op -> store, so the target is evaluated exactly once. op is the compound token itself (e.g. '+=').
