I mean honestly, are you trolling me?

Tokens like "do" and "end" are words, or more specifically keywords. Tokens
like "->" are symbols. Believe it or not for most people groupings of
letters, as opposed to symbolic characters, actually has a significant
meaning.

To me they're just syntactic items.


Can you think like a human instead of a lexer?

Let's have a look:

No. Clause bodies are delimited by "->" and "end" with ";" as an optional
clause separator. The "fun" keyword is not the delimiter and can be used in
contexts where a fun has no clause body, such as fun module:function/arity.
