    And why not "as", i.e. "t as x", as I explained once in a previous post.
    I never did get an explanation as to why this wasn't an better solution. It
    reuses a rarely-used keyword in a perfectly backward-compatible way.
    I think it's simply a typical case of a new (and not necessarily terribly
    crucial) language feature muscling in on the limited "ultra-convenient"
    concrete syntax that's available! No offence intended ;-)

    Cheers,
    Don

    It is clear that labels are a good thing ...

    But why did you use the same character ":" for types and labels !

    whit not (for instance) x:t to say that x as type t
    and l#x to say that x as label l

    the syntax l#x:t is much better than l:x : t !!

    I know that # is allready used for methods ... but some characters are
    still usable:

    ~
    £ it looks like the l of labels (but its ascii code is greater than 128,
    but is this really a problem ? probably ?)
