Initialization of state variables in list context currently forbidden

(F) Currently the implementation of "state" only permits the initialization of scalar variables in scalar context. Re-write state ($a) = 42 as state $a = 42 to change from list to scalar context. Constructions such as state (@a) = foo() will be supported in a future perl release.
