perl-Module-Metadata: code execution

It was reported that the perl Module::Metadata module incorrectly claimed that it would gather metadata about a .pm file without executing unsafe code. However, when Module::Metadata determines the version of a module, it can extract a small amount of code (if present in the $Version variable assignment) and evaluates it, which can lead to the execution of arbitrary code (the same code that module would execute to obtain the value of $Version).
