use of `only` on collection with more than one element

[baggepinnen]

I tried ExplicitImports.inspect_session() and got the error below. I hope the stack trace is useful, because I don't see a reasonable way to produce an MWE for this :sweat_smile: The last analyzed package output was

Additionally, module GenericSchur has stale explicit imports for these unused names:
- BlasComplex
- BlasFloat
- _ordschur

if that's helpful
