| Summary | 0005793: Empty blocks do not conform to Blue Book | |||||||||||
| Description |
An empty block is defined to return nil. In Squeak, it returns its last argument. This makes very little sense, and is different from other Smalltalks. I suppose you dare not change it, as who knows what code relies on this behavior. To confirm this, define the following method in any class emptyBlock ^[:x :y :z | ] value:1 value: 2 value: 3 Then create an instance and invoke it. It evaluates to 3 instead of nil. |

Just to exercize, a patch for the old compiler. Note that the NewCompiler already answer nil. |

Ah Ah, stupid, just forgot to test if statements were empty... A test.2.cs and patch.2.cs do it a little better. |
