You also can control unfolding of functions with
"cbv -[<list_of_names_to_not_unfold>]" or
"cbv  [<list_of_names_to_unfold>]".

"cbv" stands for "call by value"; it is one of Coq's reduction strategies.

Sincerely,
Kirill Taran

Dear All,

When I use the "simpl" tactic in a goal, it changes a subterm of the form
"c ++ s", with c: ascii and s: string, into "String c s" (String is a
constructor of the type string). How can I prevent simpl from doing this?

Thanks in advance,
Marcus.

You can make the string append function "++" be opaque to simpl with the declaration: Opaque append.
