No.  Nested function calls are incredibly common and do not (usually!)
have side effects; it's not very different from other algebraic
expressions.  Chained method calls are still fairly common.  It's
incredibly rare that I have to assign the same value to multiple
targets, and when I do, the little time I could save by not typing the
second assignment is offset by the increased time it takes me to look
for assignments to a variable when I come back to the code later.

It's much more of an argument of my brain not being trained to parse
it due to its low incidence than anything else :P
