    Hi,

    The myster of life isnrCOt a problem to
    solve, but a reality to experience
    - Herbert Frank, Dune

    While toying arround with our new arrow functions.
    We found that our Dogelog Player DCG implementation
    does only provide (-->)/2 and not yet phrase/3.
    Luckily the step from (-->)/2 to phrase/3 is
    relatively small, and the upcoming release will
    feature this predicate. It turns out it can be
    used for Strudel style music coding.

    After going through some rather dry scholarly
    topics such as set versus tuple oriented processing,
    we were suddently immersed in Strudel style music
    coding by passing around oscillator events inside
    a Dogelog Player notebook. Although we could not
    demonstrate the same live feedback as Strudel does,
    one can perceive the magic of composing pipelines
    by earshot proximity.

    Bye

    Hi,

    Dogelog Player has now arrow functions using a
    )/2 operator. The semantics is different from
    other offerings and based on ISO core standard
    witness calculation [7.1.1.4]. Its genesis is
    tied to formerly Jekejeke Prolog where we already
    experimented with this semantics.

    Departing from formerly Jekejeke Prolog we also
    provide ahead of time compilation. It turns out
    that this gives a better semantics, that can
    solve problems such as mutual recursion and
    nested arrows. We present a refinement for
    interpretative use, that shares the same properties.

    Nested functions have become quite popular in
    programming languages such as Python and JavaScript.
    More impressive inner functions can be returned
    as values and can then serve as closures for
    their outer context. Starting from variant
    keys and a new unnumbervars/3 predicate, we
    demonstrate the same for our preprocessed and
    then interpreted '$ANON'/n compounds.

    Bye
