Wow I couldn't believe 'scope' didn't work because it's used a 
lot for this same purpose.

But after checking DMD sources I realized that 'scope' works only 
if it precedes a new expression initializer (scope var = new 
ClassName...) which makes sense but it's really confusing.

That means in OP example 'scope' does nothing, it's just like 
'auto' and the class is heap allocated.
