Any lexical error example in elixir?

I had an exercise while reading 《PLP》. I suddenly thought that the various errors in elixir are provided by Parser(The SyntaxError). Is there any lexical error? Or what is something I didn’t notice?

LOL, I find the compile errors in the REPL, forgive me.

Actually neither is a compile error as such. The first one IS a lexical error as <a> is no legal syntax. The second one is legal syntax, it is a list of a list of one element, the variable a. The error comes from when the shell REPL tries to evaluate this and finds that the variable a has no value and there is no function a/0. This can be a bit confusing as a in this case can mean 2 things, either a variable or a function call.
