It isn't a bug. It is the feature of Perl where the last statement executed defines the return value. "sub foo {}" doesn't count as a run-time statment.

If you want "sub foo {}" to give back an empty list, then the solution is simple: 

 $ say '$^D=$^D; sub foo {}'
0
 $ say '$^D=$^D; (); sub foo {}'
 $
