Macros and other tools that need syntax privilege used `(current-code-inspector)' at the module top-level to try to capture the right code inspector at load time. It's more consistent to instead use the enclosing module's declaration-time inspector, and `var-ref->mod-decl-insp' provides that. The new function works only on references to anonymous variables, which limits access to the inspector. The real function name is longer, of course.
