By convention, most Built-In Functions (BIFs) are included in this module. Some of the BIFs are viewed more or less as part of the Erlang programming language and are auto-imported. Thus, it is not necessary to specify the module name. For example, the calls atom_to_list(erlang) and erlang:atom_to_list(erlang) are …

Because Erlang maps respect Erlang sorting order, a map such as #{1.0 => true} is going to compare equal to #{1 => true}, but you won't be able to match them one against the other. Be careful, because although the content of this section is written as based on EEP-43, the actual implementation might be lagging behind!
