+1. (I was hoping that there would turn out to be a connection between 'if' (earlier form 'gif') and 'given', but no such luck.) > But I agree that "when" and "unless" should not be in their own > library, but instead be merged into the r6rs base library. +1, and I'd like to see the trivial iterators "while" and "until" added as well. (More speculatively: how about the general Dijkstra-style iterator corresponding to "cond", which executes each guarded clause in turn repeatedly until one of the guards returns false?) -- Normally I can handle panic attacks on my own; John Cowan <[EMAIL PROTECTED]> but panic is, at the moment, a way of life. http://www.ccil.org/~cowan _______________________________________________ r6rs-discuss mailing list [email protected] http://lists.r6rs.org/cgi-bin/mailman/listinfo/r6rs-discuss
