# Continuations and generators

    Chris,

    I think your generator library should be included with Factor; what do

    you think? Your code is nicely written. You're certainly making more use

    of continuations than I do :)

    Two minor style notes; your definitions are maybe a tad too long. Also,

    can you please use the documentation comment syntax:

    : some-word ( ... )

         #! docs...

         #! more docs...

         ... ;

    That way, the comments will be visible when the word definition is

    inspected in the interpreter using "see".

    Perhaps we could use a name other than 'yield'. My game library already

    contains a word 'yield', with a different meaning. While vocabularies

    will prevent the two names from clashing, it could still get confusing :)

    Slava

    PS: I forgot to incorporate tree-each in 0.59. It will be in the next

    release.

     Sure, if you want to include it that's fine with me. Continuations

    combined with a Forth/Joy like language is an interesting combination and

    is the area I'm playing with the most at the moment. Also my main job is

    maintaining a continuation based web application server in Scheme so it

    interests me to compare the approaches of the two languages. I suspect

    that because continuations can't be compiled that some of the things I'm

    doing won't be very efficient or the best way of doing things though.

     Sure, I'll change the code. The funny thing is, although I have long

    definitions, I write them piece by piece and test each bit then combine

    them into the one definition! I need to come up with names and keep the

    smaller pieces around. I marvel at the nicely factored code in the Factor

    source code and in the Joy examples on the Joy website.

     "suspend" is a common name for this. Or maybe gen-yield?

    Chris.
