hi, IOhannes !

thanks for that info !

i often read on this list that [expr] is slower/computational more 
expensive etc. than using simple vanilla objects. why is that so ?

in theory, it would make patching more easy as it reduces the number of 
objects and cords. what are situations where [expr] makes more sense to 
use ?

thanks
