Comment (by raphink):

 Note: you should use `clear` instead of `set $path ""`.

 The problem comes from the definition of `negate_or_value` as:

 {{{
 let negate_or_value (key:lens) (value:lens) =
   [ del_negate . (negate_node . key | key . value) ]
 }}}

 For some reason, this prevents from using the `negate_note . key`
 alternative when setting the node. Changing to:

 {{{
 let negate_or_value (key:lens) (value:lens) =
   del_negate . [ negate_node . key ] | [ key . value ]
 }}}

 would work, but then:

 {{{
 test Sudoers.parameter_integer_bool
     put "umask = 022"
     after set "/umask/negate" ""  = "!umask"
 }}}

 would stop working, as it would not be possible to have both a value and a
 negate node.
