Are you sure keys is an lvalue function?

I get no complaint in scalar assignment, but no indication it worked, either. List assignment gives, 

$ perl -Mwarnings -Mstrict -e'keys( my %foo) = qw/foo bar baz/;print %foo'
Useless use of a constant in void context at -e line 1.
Useless use of a constant in void context at -e line 1.
Argument "baz" isn't numeric in scalar assignment at -e line 1.
$
