guess this is coroutine related.. why can i not do suspend operator get(id: String) and is there any way to use operator overloading with suspending functions ?

It is allowed on a per-case basis. It works with invoke operators for example, because it looks like a function call. I think I understand why the get one can't suspend as it'd be a bit weird to have square brackets take a long time. get operators is almost always used for in-memory structures like arrays, lists…

It is merely a bug: https://youtrack.jetbrains.com/issue/KT-15403

seems like i starred the issue in the past and then forgot about it, hah

I personally would not like this. If I type in someDataStructure[10] I would expect 10th element to be retrieved immediately instead of performing asynchronous operation. someDataStructure.getAsynchronous(10) would be more appropriate.

I don't see a problem with adding the option. Individuals and teams can have their own rules regarding it.

@Matej Drobnič This is a matter of consistency. Currently, some operators can be suspend and some cannot. Ideally, all of them should be able to be suspend.

Suspend does not equal block, so I think suspending call is OK for get operations
