Dots between identifiers without spaces are your usual key value coding 
keypath. 

#### Example 1
```
{{ bag.a }}
```

If you leave spaces between the dots, the functionality expands, so
that you can interpose arbitrary objects

#### Example 2
```
{# Then you can also interpose methods if you want  #}
{%
   z = [NSDictionary dictionaryWithObject:@"VfL Bochum 1848" forKey:@"c"]
   y = [NSDictionary dictionaryWithObject:z forKey:@"b"]
   x = [NSDictionary dictionaryWithObject:y forKey:@"a"]
   {{ x . a . b .c }}
   {{ x . a . [self objectForKey:@"b"] . c }}
%}
```
