Detailed Description
A decomposition declaration.
For instance, given:
int n[3]; auto &[a, b, c] = n;
the second line declares a DecompositionDecl of type 'int (&)[3]', and three BindingDecls (named a, b, and c). An instance of this class is always unnamed, but behaves in almost all other respects like a VarDecl.
