When working with structures nested that deeply you might consider IsDefined
instead.
<cfif IsDefined('session.currentUser.permissions.' & arguments.path)>
It's not a best practice necessarily, but it would prevent a whole bunch of
StructKeyExists calls.

Subject: Finding the value of a key in a nested structure
Ok, my brain is hurting - I know this should be possible, but I can't quite
get the syntax.
I need to pass a string (a path to a structure which contains a boolean in
the session scope) into a function, which then checks the value:
i.e
<cfif checkPermission("email.send.all")>
Show a form or page
</cfif>
<cffunction name="checkPermission">
<cfargument name="path">
<cfif session.currentUser.permissions['#arguments.path#']>
<cfreturn true>
<cfelse>
<cfreturn false>
</cfif>
</cffunction>
So in this instance, CF is looking for
session.currentUser.permissions['email.send.all'] - i.e a structure key name
of 'email.send.all' , rather than
"session.currentUser.permissions.email.send.all"
Is there an elegant solution to this problem?
