dest_thy_constTerm.dest_thy_const : term -> {Thy:string, Name:string, Ty:hol_type}
Breaks apart a constant into name, theory, and type.
dest_thy_const is a term destructor for constants. If
M is a constant, declared in theory Thy with
name Name, having type ty, then
dest_thy_const M returns {Thy, Name, Ty},
where Ty is equal to ty.
Fails if M is not a constant.
A more precise alternative to dest_const.
