The "... and ..." multiple-declaration isn't at the str_item level but
at the ctyp level. You should use <:ctyp< $..$ and $...$ >>. Moreover,
it appears that the type declaration node in the AST (Ast.TyDcl) does
not have a quotation syntax : <:str_item< type $..$ = $...$ >> won't
work.
let type_chain _loc lst =
let decl (name, constructors) = Ast.TyDcl(_loc, name, [],
constructors, []) in
<:str_item< type $Ast.tyAnd_of_list (List.map decl lst)$ >>
