> With this change, commands such as 'guix build' or 'guix package' report
> obvious package-level cycles upfront. Derivation-level cycles are not
> detected.
>
> * guix/packages.scm (&package-cyclic-dependency-error): New condition
> type.
> (package-transitive-supported-systems): Define 'visited', check it, and
> parameterize it.
> * guix/ui.scm (call-with-error-handling): Handle
> '&package-cyclic-dependency-error'.
> * tests/packages.scm ("package-transitive-supported-systems detects
> cycles"): Add test.
