Compensate for the fact that dominance does not correspond
exactly to scoping. A definition can dominate a use, but when mapped
in a naive way to constant definitiion and its use, the definition
name goes out of scope by the time you reach the use.
This is correct for storable types.

The process of passing the module through this reader, the WGSL semantics,
