Hi Maarten,

When add-functions is used repeatedly with the same function. This fonction
appears several times in the function list.

Here is my code.

 >> rx: context get-rugby-service tcp://192.168.1.53:8001
 >> psw: "pat665"
 >> rx/remove-functions "pat665" [double]
 == none

Once removed the function cannot be used anymore.

 >> rx/double 3
 ** User Error: Rugby server error: Unsupported function: [double 3]
 ** Near: make error! rejoin ["Rugby server error: Unsupported function: "
     mold statement]
 >>

Restoring the double function is easy with add-functions

 >> rx/add-functions "pat665" [double]
 == none
 >> rx/double 3
 == 6
 >>

Calling add-functions repeatedly seems armless...

 >> rx/add-functions "pat665" [double]
 == none
 >> rx/add-functions "pat665" [double]
 == none
 >>

In fact experimentation shows that after three add-functions, the added
functions really appears three times on the function list.

 >> psw: "pat665"
 == "pat665"
 >> f-list: rx/functions? psw
 >> foreach f-name f-list [print f-name]
 triple
 get-stubs
 exec-code
 add-functions
 remove-functions
 functions?
 start-profiling
 profile-data
 reset-profiler
 ping
 set-pass-phrase
 double
 double
 double
 >>

However only one remove-functions suffice to remove the function.

 >> rx/remove-functions "pat665" [double]
 == none
 >> rx/double 3
 ** User Error: Rugby server error: Unsupported function: [double 3]
 ** Near: make error! rejoin ["Rugby server error: Unsupported function: "
     mold statement]
