@spec multiline_list_to_utf8_binary(list()) :: {:ok, binary()} | {:error, term()}

Variant of list_to_utf8_binary, but specifically for handling multiline strings

@spec split_multiline_list([char_or_code()], esc_multiline(), [esc_multiline()]) :: [
  esc_multiline()
]

Splits a multiline list, this will mark each line with its escape status, a line with a :esc status should not be used for whitespace trimming/dedent, as it was explictly set.

One thing to note is all lines in the returned list start with a newline if its not the first line.

The returned array is always reversed, so the last line will be first

@spec split_spaces(binary(), list()) :: {spaces :: binary(), rest :: binary()}

Splits off as many space characters as possible

Check if a string is a valid identifier (that is a plain unbroken character sequence)
