| 9 | + | #### For-in loop support | |
| 10 | + | ||
| 11 | + | - **Overview**: *for-in* loops allow for easy iterating over the contents of a container type, as well as over some primitive types (arrays, strings, sets) using a uniform syntax. | |
| 12 | + | - **Notes**: The basic implementation is Delphi-compatible, but in addition FPC also supports some extra functionality. This functionality is described on the page below. | |
| 13 | + | - **More information**: [[for-in loop]] | |
| 14 | + | ||
| 15 | + | #### Sealed and Abstract classes | |
| 16 | + | ||
| 17 | + | - **Overview**: A *sealed* class is a class which can not be inherited by other classes. An *abstract* class normally cannot be instantiated, but for compatibility with Delphi *abstract* does nothing at the moment. | |
| 18 | + | - **Notes**: Delphi-compatible. | |
