Well, that would be *another* measurement – related but not the same. 
Even harder to measure, I'm sure. The cognitive load of a menu-driven 
scripting system such as early versions of Flash was very low indeed 
(despite being rooted in an animation timeline concept) – but it was 
itself very limited. I think it's good that this Southern Cross U 
comparison didn't go beyond a set of actual application development 

I find the idea of cognitive load measurement extremely interesting. If 
something's Just Damn Tough to learn it's simply less accessible. It's 
the broad accessibility of xTalk that I have always found so exciting, 
from my HyperCard 1.x and SuperCard 1.x days onwards... and it's the 
relative Just Damn Tough-ness of Objective C that made me bail on my 
attempts to learn it a few years back. The cognitive load was too much 
for me. :-/
