I was referring to the "someone who has a constraint that 
prohibits the use of a GC" part and my reasoning is that someone 
with such a use case probably wouldn't find solutions in *Phobos* 
meeting their demands because the result would be too 
bloated/slow. And as such they would probably tailor their own 
optimized solutions.
With no word did I claim that it's impossible to write production 
systems in D with a GC linked in.

Thank you. That's what I'm saying - or trying to say, at least.
