in thread Can I avoid loops getting the single value from a hash without knowing the key?

Hmm, maybe I misunderstood, but this is difficult to follow. On one hand you ask for a value of a hash with one entry, OTOH you state this situation is simplified, in your real code there are more entries.

But if there are multiple entries in the hash, LanX's suggestion will put the value of a randomly choosen hash entry in $value. This might not be what you want.

So I suggest defensive coding:
first check if the hash only holds one entry if (1 == scalar keys %hash) before (blindly) retrieving a value.
