I have a hash of hashes of hashes of arbitrary depth as part of a class.

So, to access a specific element, I have something like $hash{a}->{b}->{c}->{d}, I would like to write a method which would allow me to access the same element with the identifier 'a.b.c.d' - so far I've come up with either doing it as a recursive sub or constructing a string and using eval.

Are there other ways of doing it? I am basically looking for the least expensive way.
