{ s/\.\d+//g; $1=>$2 if/(.+)\s+\|\s+(.+)/; }

This will supply 2 elements to properly populate the hash if the match succeeds.

However, on match failure, the return value is undef() (I think), but the important thing is that a single (ODD NUMBER) value is returned, so the hash is not happy.

Update:
I would correct it as : 

{ s/\.\d+//g; /(.+)\s+\|\s+(.+)/ ? ($1=>$2) : ()  }
