You mean the first checking form `SymbolicRegion`, then get its symbol, check
for `SymbolRegionValue`, then get its `TypedValueRegion`, check for
`DeclRegion` and use its `Decl`? This sound waaay more complicated and less
readable. I am not sure which are the side cases: is it always
`SymbolicRegion`? Is the `Symbol` of `SymbolicRegion` always a
`SymbolRegionValue`? Is ithe `TypedValueRegion` (the return value of its
`getRegion()`) always a `DeclRegion`?
