In a future release, the text representation of atoms might be allowed to contain any Unicode character and atom_to_binary(Atom, latin1) will fail if the text representation for the Atom contains a Unicode character greater than 16#FF. erlang:cancel_timer(Ref) cancel_timer(Ref) cancels a timer, where Ref was returned by either send_after/3 or start_timer/3.If the timer was there to be removed, cancel_timer/1 returns the time in ms left until the timer would have expired, otherwise false (which may mean that Ref was never a timer, or that it had already been cancelled, or that it had already delivered its message). Erlang/OTP; ERL-860; erlang:register/2 only accepts atoms as keys File format for Beam R5 and later Last update of this document: Mar 1, 2000.

Can't the parser/printer fix this for us? Well yes, it could and it actually isn't that difficult. We fix the parser/printer so a '-' in an LFE atom becomes '_' in the Erlang and vice-versa. atoms that are the same also share a single entry in the table.

Once an atom has been created, it lives as long as the Erlang node is running. An easy way to crash  Elixir, on the other hand, uses the former for naming variables, and the latter are treated as atom aliases. Atoms in Elixir always start with a  But in functional language such as Erlang, parallel processes do not have mutual Booleans: Atoms true and false are used to denote Boolean values. Optional fields either contain a value or contain the atom 'nil' .

Elixir, on the other hand, uses the former for naming variables, and the latter are treated as atom aliases. Unlike Elixir, atoms in Erlang aren’t prepended with a :. atoms are named much like you would name a variable in Elixir. So an atom must begin with a lower case letter, can include numbers, underscores, and the @character. Also, unlike Elixir, to define an atom with spaces or begin with a capital letter, you use single quotes. Atoms in the Erlang AST are represented as {:atom, line_nr, atom_name}, where line_nr is the line number in which the atom occurs.
