Ecaml_value.FormSourceAn Emacs "form", which is a Lisp object that is intended to be evaluated. (Info-goto-node "(elisp)Forms").
include Value.SubtypeWe expose private value for free identity conversions when the value is nested in some covariant type, e.g. (symbols : Symbol.t list :> Value.t list) rather than List.map symbols ~f:Symbol.to_value.
eq t1 t2 = Value.eq (to_value t1) (to_value t2), i.e. eq checks whether the Emacs values underlying t1 and t2 are physically equal. This is different than phys_equal t1 t2, because we don't always wrap eq Emacs values in phys_equal OCaml values. I.e. phys_equal t1 t2 implies eq t1 t2, but not the converse.
eval_string string = eval (read string)
A function call, macro application, or special form. (Info-goto-node "(elisp)Classifying Lists").
