Well, I do not think so. Because I do not understand why unnest does 
what it does, and I am not the kind of programmer who blindly 
implements "this one weird trick that makes postgres 260 times faster" 
from SO or a blog. I want to know what happens, and why, and often 
enough that sort of extra questioning leads to 4000 times improvement 
instead of 260.
