Description of problem:
On Fedora Rawhide, the perl module does not have the default stream set. Because there are multiple streams available for this module, DNF will not install using `dnf module install perl`. It will report an error instead. Since modules should be able to install using the aforementioned command, I consider this a bug.
Steps to reproduce:
1. dnf module list perl
Modules should have the defaults set.
If you did not set the defaults on purpose, please share the reason and confirm that explicitely.
perl module cannot have a default stream because Perl is also packaged in the classical non-modular repository and Fedora does not allow modules to override non-modular packages.
