in reply to Dereference a hash constant

I don't believe you can make this work. You're defining foo as a hash reference. You'll have to figure out a way to dereference foo without making the parser think you're referring to a variable named %foo and how to avoid creating a new hash reference on every invocation. (I made a lovely infinite loop this way.)

This assumes I even understand what you're trying to do; your example code makes little sense to me. What are you trying to do?

Re^2: Dereference a hash constant

    I have a hash which has constant key/values, so I thought of making it as a constant hash. But now I realized it is impossible to iterate through a hash ref. Thanks.

      Nuh uh! See 802571.
