in thread Can you explain the result?

There are also goto, next, last.

In the context of the vague assertion I was replying to there is no difference in my opinion. When 'return' is called it does it's job just as when 'open' is called. The difference the OP doesn't seem to grasp is that when return is called, anything after it in that block doesn't execute (how could it?) This is by design and is how other languages work.

    Sure, but all of these four are keywords, and not functions - this is what makes them special.

    But in the context of parsing, they are not really treated that special from (prototyped) functions, so there is no difference in that sense. Well - I'm not sure whether it's possible to pass a label to a function. My naive approach doesn't pass strict:

    use strict; sub bar($) { print shift }; FOO: { bar FOO; };
