Maybe I missed the momentum of the discussion but I would like to see  
something similar in Lua.
It encourages to use RAII, and reduces the scope of the variable.

We already have in Lua some form of assignment expression in... for loops.
No one has been complaining about that.

Another example is C++17 that allows you to do something like:

if( auto foo = get_foo() ; foo.bar() == 42 )
{
  foo.baz( 1337 );
}
