In elisp, symbols serve as fundamental data structures that are more foundational compared to strings. This distinction often caused confusion for me until my encounter with the read function.

 ~ $ (type-of (read))
 symbol

The fact that the read function yields symbols instead of strings from user-input was a delightful revelation. This discovery convinces me that the fundamental nature of symbols in elisp when compared to strings.

    I assume the read function initially reads the input as a symbol type, and subsequently, during the evaluation process, converts it into the corresponding data type. This two-step process involves reading the input as a symbol and then evaluating it to obtain the appropriate type.
