I got (as expected) assignment, so I assumed you were not expecting
assignment.
Weird, this is what I'm getting in either R 2.13.0 or R 2.12.0:
> library(zoo)
Warning: package 'zoo' was built under R version 2.13.1
> x = zoo(1:5, as.Date('2001-01-01')+1:5)
> x[as.Date('2001-01-05')]
2001-01-05
4
> x[as.Date('2001-01-05')] = 0
> x
Error in dimnames(x) <- dn :
length of 'dimnames' [1] not equal to array extent
I get
> x
2001-01-02 2001-01-03 2001-01-04 2001-01-05 2001-01-06
1 2 3 0 5
As did another. So you are the odd man out and the burden is on you to
show why updating to a current version does not solve your broken
installation.

Why doesn't this work?

I think this is especially bad because it doesn't cause an error.
It lets
you do something to x, but then you can't see x again to see what it
did.
It did exactly what I expected it to do. What was the "this" that
you think was bad? I hope you are not asking that R ask users to
confirm every assignment with a popup window.
