Papercut with state variable references

[rohitkulshreshtha]

It isn't possible to do something like this:

let all_data: &HashMap<...> = (&#namespaces).as_reveal_ref();

It results in the error message:

150 |                 let all_data: &HashMap<Namespace, TableMap<RowValue<Clock>>> = (&#namespaces).as_reveal_ref();
    |                                                                                 ^^^^^^^^^^^                - temporary value is freed at the end of this statement
    |                                                                                 |
    |                                                                                 creates a temporary value which is freed while still in use

The current workaround is

let namespaces = &#namespaces;
let all_data: &HashMap<Namespace, TableMap<RowValue<Clock>>> = namespaces.as_reveal_ref();

A fix would be very nice to have.
