FYI: In painlesstraits we use a different approach, where we test 
whether it is a function (with isSomeFunction) and then test for 
the property attribute:

https://github.com/msoucy/painlesstraits/blob/master/source/painlesstraits.d#L173
```
static if (isSomeFunction!(T))
         {
             return (functionAttributes!(T) & 
FunctionAttribute.property);
         } else
             return false;
```
