dump and dput but have the same behavior but dump has an extra option
'evaluate'. From the documentation, 'evaluate=TRUE' looks like it should
force promises to be evaluated, ie convert 1:6 to be c(1,2,3,4,5,6).
Both 1:6 and c(1,2,3,4,5,6) are expressions, and they evaluate to
different things. (1:6 is an integer vector, the other is a "numeric"
vector, stored in floating point.) dump() is just trying to give more
concise output. Look more closely at Peter's example.

I think that either my understanding of what a 'promise' is and what it
means to be evaluated is flawed, or the evaluate option in the dump command
is broken.
