We have some async properties (using @property) and some usual ones. We have to use hy to check if one is async or not using asyncio.iscoroutine function. The problem is we have to use getattr and not . operator, since dot will call the property inner function. We want to change our hy code without breaking the DSL used in other projects, that is, we do not want to use string notation (double quotes) for attribute name and therefore we need to write some macro working just like . but internally calls getattr.

```
=> (defmacro attr [obj attr] `(getattr ~obj '~attr))
=> (attr 5 real)
Traceback (most recent call last):
  File "stdin-5bbedde10a6366314d9be4bd343639582b4d0748", line 1, in <module>
    (attr 5 real)
AttributeError: 'int' object has no attribute 'real'
=> (. 5 real)
5

```
