(variable-reference->resolved-module-path
 (#%variable-reference))

If the result is not #f, you can then extract the module name with
`resolved-module-path-name'.


[I see that the docs say that the expression above will raise an
 exception if the current namespace is a top-level namespace, instead
 of a module namespace. In fact, I had changed it to produce #f in that
 case, and I'll fix the docs.]
