Always interesting when while working on a specific problem resolution, 
coincidentally the circle gets squared. In this case, while building one thing, 
it lead down the rabbit hole of async generators which surveyed everything from 
https://www.dreamsongs.com/WorseIsBetter.html to https://okmij.org/ftp/Streams.html 
and much, much more until it led back to an SO post that had a related SO post that
was quite literally almost the same thing I had originally set out to build (!). 

I should probably compile all the bookmarks for any potential shared future benefit, 
but note this particular generator function is almost *entirely* modeled on the work of Redu from:

// Using zx to manage background redis server (for development purposes mostly, and doesn't require sudo (except prior to, when disabling redis-server autoboot initially)). 

// ( cli user input loop logic via zx question likely suggests its own reusable component TBD; also something similar for zx error handling). 

// notice while redis-server cmd is used to start, to cleanly stop redis-cli shutdown is used. Avoids manipulating systemctl (as I saw on several guides) which when doing so tended to spontaneousily crash my system).  

// in reverse order for readible coherence, all relative directories flattened for simplicity.

// assume npm esm project... with a script defined:
// npm script: "redis-server": "node index.js" (see below)

BNT-2 - Invoice Bounty Task Check Sheet

This is a list of all the tasks specified as part of the bounty to be completed before submission for approval.

They can be originally found at BNT-2: Invoice Canister #2.

This was created to make it easier to know what needed to be done as to verify everything has been completed.

Example A (**verbose in-method-body comments**)

  public shared ({ caller }) func verify_invoice(
    { id } : Types.VerifyInvoiceArgs,
  ) : async Types.VerifyInvoiceResult {
    switch (getInvoiceIfAuthorized(invoices.get(id), caller, #Verify)) {
      // Caller is not authorized or invoice not found.
      case (#err err) return #err(err);
      // Caller is creator or on invoice's verify permissions list.
      case (#ok invoice) {

You can drop the ICP.MockLedger if you want to skip importing the Aviate Labs libraries and just use it for ICRC1.

uses zx as ilocal project dependency; zx can also 
be used by including its shebang at the beginning
of the mjs using it--in that case can be run by
> chmod +x file.mjs
> zx file.mjs

What is objected orientated programming?

"Object oriented programming is a technique of writing code that encapsulates complexity by enumerating data structures with an intrinsic implementation so that they can generally interface."

    private void copyFile(String fromPath, String fileName, int file) {
        InputStream in = null;
        OutputStream out = null;
        try {
            in = getResources().openRawResource(file);
            out = new FileOutputStream(new File(fromPath, fileName));
            byte[] buffer = new byte[1024];
            int read;
            while ((read = in.read(buffer)) != -1) {
                out.write(buffer, 0, read);
