So the (real) continuation (saved in a global variable) could be called even after the body of call_cc returned?

I see. If the function call activation frames are treated just like everything else, and there is no special action for "going out of scope", keeping a live reference to it is just like any other closure.

In Perl 6 we'll have to watch it because of the mechanism for having block-exit code in a finally clause or added dynamically by a caller. What would that do, if one can exit more times than enter?! (I have some ideas of what it should mean, but that's for another thread)

to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
