Argh, I hate source code "comments" #NotAllComments
Consider this:
```
provider "azurerm" {
subscription_id = "0301c5d5-9685-4550-b375-1aaf8f7c2ada" #example-com-subscription
features {
}
}
```
This comment is crap. Especially since the same UUID is used below /again/ (this time, w/o comment). If you notice yourself writing comments next to magic numbers... use variables (or constants).
Then you can write:
```
subscription_id = var.example-com_subscription_id
```
This is immediately clear to the reader, reduces change anomalies and separates logic from data. Gnarf.
