I don't think so... take for example the following
if locking could be done in <CFSCRIPT/>
<CFIF serviceAvailable('borkyService')>
do stuff, we don't care about how serviceAvailable() does it's
job, just that we ask for a service and it
tells us if it is available
internally, serviceAvailable must perform a named lock around say
some code accessing a global structure that
holds the services that are currently configured in the website,
say, APPLICATION.Services
but this calling section of code doesn't care aboutt that we don't
want to know how the job is done, only that it is
</CFIF>
whereas without the locking I have to do
<CFLOCK ....>
<CFIF serviceAvailable('borkyService')>
now we have to split the implementation of
serviceAvailable, no longer do we not care how it is done, we have to
be a part of it. If we have to change the lock name for
example, we can't just change it in serviceAvailable() we have
to change it here, and anywhere else we use serviceAvailable()
not to mention, all the code in this if statement is now
holding, unnecessarily, a lock, so that no other block using
serviceAvailable() is able to run
</CFIF>
</CFLOCK>
in conclusion I think that not having locks in CFSCRIPT is causing the
break of scope.
