Hmmm... I needed this for dealing with a crypto ledger where I have tons of explicit lots, but I don't want to have to enumerate all of them in the...

One improvement I can see right away is to use a regex object for the account keys, rather than a string. The current implementation re-builds the reegex object (`std::regex`) every...
