[1,2,3] is called a literal array in many languages like for instance JavaScript.

Since Perl has both an explicit $reference and a @list form of its data structures, it might be difficult to point out "the" literal form.

For the same reason why it's prevented with other readonly values like literal scalars ... to catch bugs with aliases.
