[R] sibling list element reference during list definition

Can the value of a list element be referenced from a
sibling list element during list creation without the use
of a temporary variable?

The following doesn't work but it's the general idea.

> list(value = 2, plusplus = $value+1)

such that the following would be the output from str()

List of 2
 $ value   : num 2
 $ plusplus: num 3
