myobj

For example, in C++: myobj a; somefunction(a); That copy constructor might trigger a database hit to create a new object if myobj was some sort of ORM.

How could anyone refactor something like this in Python getattr(myobj, 'myprop', None) Where mypropis dynamically generated?

My claim is that, if I call `foo(std::move(myObj))`, it is statically knowable if `foo` receives a copy of `myObj` or whether it is moved to it.

In python, that would look like: a = myobj() somefunction(a) def somefunction(p): p = copy.deepcopy(p) In that version I'm now implicitly providing that copy.

Pretending that javascript is immutable, I think it would probably look something more like contextObj = monadBox(myObj) // someContextReturningFunc gets myObj as its argument from contextObj and generates newContextObj newContextObj = monadBind(contextObj, someContextReturningFunc) newNewContextObj = monadBind(newContextObj, someOtherContextReturningFunc)...

It looks like monads are just a way to call functions in difference context, in js map(myObj, someFunc, contextObj) Or am I missing something here?

In addition, when you don't care about null/not found, you'll have the dual problem and you will need to flatten nested sum types as the List find would return `Option<Option<MyObj>>` - `flatten`/`flat_map`/similar need to be used regularly and aren't necessary with anonymous sum types that do this implicitly.

Now, if I give `foo` a pointer to myObj, it could of course choose to copy or move from it later and based on runtime info - but this is not the discussion we are having, and `std::move` is not involved from my side at all.

When you want to distinguish `MyObj??` then you'll have to distinguish the optionality of one piece of code (wherever your `MyObj?` in the list came from) with some other (list find) before "mixing" them.

However, false ifTrue: ["Debug this" myObj:= MyClass new.

Is it myobj.addNumber(42, withString:"Hello World")?

$scope.myObj = {x: 2}; <div ng-bind="myObj.notHere"></div> (forgive me if my syntax is off a bit, haven't written angular in awhile) The example he gave is an object not having a properly on it that he's trying to access.
