Re: Mutating existing persistent data

That’s interesting. If you declare a variable persistent
and the modified a cons deeply nested inside what the
variable points to, are you able to store the mutation
as a single (log operation)?

The only way I can come up with solving this is to
maintain a topological order of the object graph,
if you’ve already done so, that’s impressive.
