Fine!  (Btw, which one did you pick?)

No, that's the only reason.  Note also that this is not 100% safe
because elements in the Hash are not frozen so for a more robust
solution you would need to recursively freeze everything contained in
the Hash.  I still like it to freeze the Hash to avoid simple errors
and document in code that this is really meant to be constant.  (At
least that's what I guessed you wanted them to be.)

Kind regards
