Raku Programming/Property Blocks

Property BlocksEdit

We've seen in the previous chapter the special CATCH block that is used to handle exceptions thrown from the block that the CATCH lives in. In addition to CATCH, there are a number of other special property blocks that can be used to modify the behavior of the block they live in.

Property blocks are lexical in nature: They modify the behavior of the block they are defined in, and they do not effect outer scopes.
