A restricted version of :erlang.binary_to_term/2 that forbids executable terms, such as anonymous functions. The opts are given to the underlying :erlang.binary_to_term/2 call, with an empty list as a default. By default this function does not restrict atoms, as an atom interned in one node may not yet have been interned on another (except for releases, which preload all code). If you want to avoid atoms from being created, then you can pass [:safe] as options, as that will also enable the safety mechanisms from :erlang.binary_to_term/2 itself.
