Line 498:
=== Return from a Block ===
it should be noted that a "ˆ" (return) inside a block will return from the enclosing method, NOT only from the block.
This makes it possible to pass a block to eg. collections to enumerate elements up-to and until some condition is met. For example, if we need a helper method, which returns the first element from a dataset which meets some condition, we can write:
<lang smalltalk>
