Do you realize that lisp is actually a very small core language?
(eval fits on a single page).

All the rest, the lisp programming language you _use_ is not this core
lisp, it's only _MACROS_!  And for them it is essential to have
homoiconicity.

Even if you don't write macros yourself you are constantly using them.

Since (k . v) is not a form, what you call 'function' above MUST be a macro!
