If serviceAvailable() requires the use of the external variable
application.services I would say that it is a Bad Thing (TM) if you can
invoke it like serviceAvailable('borkyService'). The UDF should be
modified so it has to be invoked by sending all external variables,
serviceAvailable('borkyService',application.services)

I think bad UDF implementation is causing break of scope in your example
for the reasons stated above, and I completely agree with Birgit.
