Well, the domain of Perl hash keys is limited to its primitives - which 
are simple scalars, or values that can be cast to scalars.

Multidimensional constructs are not implicitly serialised to one-way 
hash codes, as for example is done with Java objects and the hashCode() 
method.

I am assuming dial plan data structures and variables are not supposed 
to be much different in terms of their complexity.
