[ 23062]
First stab at explaining that CLONE may get more parameters in future.
More eloquent rewording desired. Patches welcome.

Randal notes:
"perldoc perldelta" still says 5.8.3 to 5.8.4, even though there
*is* a "perldoc perl583delta" properly.
This is because perl584delta still thinks it's the perldelta
