I want that code to crash and burn if it is ever called, because it means the NIF is not loaded properly. That is, what is the correct specification to give here such that the underlying call to enacl_nif:crypto_box_keypair() returns the right type, without getting the dialyzer all confused due to the replacement code in the erlang module?<span class="HOEnZb"><font color="#888888"><br><br clear="all"><div><br></div>-- <br><div>J.</div>
