Thanks. Fixed.

Yes, there's nothing special about lvalue subs. f() doesn't cause the list assignment operator to be used, but (f()) does.

$ perl -wle'sub f :lvalue { $x,$y } f()=(4,5); print $x,$y' Useless use of a constant in void context at -e line 1. Use of uninitialized value in print at -e line 1. 5 $ perl -wle'sub f :lvalue { $x,$y } (f())=(4,5); print $x,$y' 45
