[BUG] "Code block with parameters" lowers arguments without semicolon

[DyXel]

Describe the bug Title.

To Reproduce Steps to reproduce the behavior:

1. Sample code

   main: () = {
   (copy a: std::string, copy b: std::string) {
       a = "Hello, ";
       b = "World! ";
       std::cout << a << b;
   }
   }

2. Expected result - what you expected to happen I would expect one of these to happen: a. cppfront errors out and tells me that I need to initialize the parameters (if thats the intention) b. They are lowered wrapped in the deferred_init class and the usual lifetime initialization semantics apply c. they are lowered as is, just with the extra ;
3. Actual result/error outputs the following c++ code (redundant parts omitted):

   auto main() -> int{
   {
   std::string a // <- whoops!
   std::string b // <- whoops!
   {
       a = "Hello, ";
       b = "World! ";
       std::cout << cpp2::move(a) << cpp2::move(b);
   }
   }
   }

   Additional context I call this "Code block with parameters", but I don't know if there's a better name for them. I checked the documentation and they are referenced as "more RAII locally-scoped variables" and "local and immediate (aka 'let' in other languages)" which doesn't roll off the tongue too well 😛
