Set-wormhole-data
Sets the wormhole data object in a wormhole status object
General Form: (set-wormhole-data whs data)
See wormhole. Whs should be a well-formed wormhole status;
data is arbitrary. This function returns a new status with the same
entry code as whs but with the new data. It avoids unnecessary
consing if the data for whs is already set to data. This function
does not affect state or a wormhole's hidden status. It just returns a
(possibly) new status object suitable as the value of the lambda
expressions in wormhole-eval and wormhole.
