... and '$( ... )' is a fork?  Yes, clearly by your example.  Yeah, it 
spawns another shell, yes?

Holy cow, 1500 X ??

I like efficiency in principle even if in practice it's miliseconds. But 
I have to keep appending to the list for each line, can the 'print -v 
var' method handle that?  Not important, but it would be satisfying to 
do the whole thing in the current shell.
