No. Example Re^3: RFC - FAQ for Modification of a read-only value attempted Also see perlsyn (RTFM is good for you):
If any element of LIST is an lvalue, you can modify it by modifying VAR inside the loop. Conversely, if any element of LIST is NOT an lvalue, any attempt to modify that element will fail. In other words, the "foreach" loop index variable is an implicit alias for each item in the list that you're looping over.
