Hi Duncan,
I did nothing between running the first two and the last two. The following
is the output:
> msg <- "old"
> delayedAssign("x", msg)
> msg <- "new!"
> x
[1] "new!"
> msg <- "old"
> delayedAssign("x", msg)
> msg <- "new!"
> x
[1] "old"

If I run these four commands together, x is "new". If I run the first two
commands first and then run the last two commands, x is "old".
I just cannot figure out why.
