code folding

[Entity325` via Digitalmars-d-learn]

FYI,
static if(true)//comments are great for adding some context to 
your code.
{
   //stuff
}
and
{//let's toss a comment on the scope declaration!
   //stuff
}
are functionally equivalent in my IDE. Both will fold down to 
only the top {(good), and both create a scope outside of which no 
declarations inside them are visible(potentially undesirable 
side-effects).

If you need to sequester your code, you really should just toss 
it into a library and import it from there(no side-effects).
