Hi there,

I have a hash with various keys and values that are strings.

If the key exists, the following works: h["foo"] += "bar"

But if the key does not exist, I get an error.

Is it possible _in one statement_ to cover both the cases where the key
does exist (as above) AND the case where the key does not exist - and in
this situation I'd like the new key and value pair to be created in the
hash.

Any help gratefully received!
