Re: Optional and Default Parameters

    From:           Seth R. Goldman <seth@UCLA-CS> (?Invalid address syntax)
    Are there any plans to include something on the order of Zetalisp &Optional
    field in the parameter list for functions?  I (and others) find it
    mildly annoying to have to explicitly provide streams to operations such
    as print, display, and format as one example.  It would be nice to be
    able to have the stream argument be optional and have some reasonable
    default (i.e. standard-output or terminal-output).  This kind of facility
    would also be useful for user applications as well.
I agree completely.  There are plans to do this, but it has low
priority.  Mild annoyance is not enough to motivate something that
would require this much work.
