Hi monks

slice is of course a powerful expression in perl, which many other languages borrow it. but why each/keys/values can't work on it? is difficult to implement? Please enlighten me. 

C:\Users\Administrator>perl -E"my @bb = 1..10; for(keys @bb[1..5]){say
+;}
Experimental keys on scalar is now forbidden at -e line 1.
Type of arg 1 to keys must be hash or array (not array slice) at -e li
+ne 1, near "])"
Execution of -e aborted due to compilation errors.

C:\Users\Administrator>perl -E"my @bb = 1..10; @cc = @bb[1..5]; for(ke
+ys @cc){say;}
