I'm not too familiar with DUB, so I'll pass on this one, but a 
clarification:

--gc-sections isn't referring to D's builtin GC, but tells the 
linker to remove "garbage sections" in the executable, i.e. those 
that aren't referenced from anywhere. Apart from the name (and 
that the underlying ideas are similar), those two have nothing to 
do with each other.
