	Sorry, but that's nonsense.  In the message you're replying to, what 
I'm arguing "doesn't matter" is the WORD used to do the postfixing.  Are 
you seriously saying that the "neurological model for working memory" 
means that "x + y where x = foo" is easier to understand, on a 
fundamental neurological basis, than "x + y given x = foo"?  Since 
you're the one who was advocating for objective measures, I'm sure 
you'll understand if I want some solid objective evidence for that!

	If you're saying that the entire concept of postfixing the givens 
(rather than putting them before the expression) creates greater 
cognitive load, then how do you explain the use of this format in the 
Wikipedia articles I linked, not to mention various math papers, texts, 
etc. throughout the world?

	Finally, even if we allow that postfixed-givens does increase cognitive 
load on a single, initial reading, that's not sufficient.  Part of what 
I'm saying is that on LATER readings it's faster to see the overall 
expression first, because you don't have to plow through the definitions 
of the givens.
