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).
