There is no longer a <:str_item< declare ... end >> construct, you can build str_item sequences using the empty str_item <:str_item<>> and the sequence <:str_item< $st1$; $st2$ >>. <:str_item< $list:sts$ >> should even do the job when having a list, but that's just a sugar over folding with these two constructions (Ast.stSem_of_list).
