R help - Jan 1999 - Pairlist & Dataframe

Is this a feature/bug or am I missing something:

    R : Copyright 1999, The R Development Core Team
    Version 0.63.2  (January 12, 1999)
    ......
    
    > ls()     
    character(0)
    > x <- NULL
    > x$x1 <- rnorm(10)
    > x$x2 <- rnorm(10)
    > mode(x)
    [1] "pairlist"
    > as.data.frame(x)
    Error: can't coerce pairlist into a data.frame

Thanks,
E. S. Venkatraman

This is a bug. Pairlists shouldn't show up in "normal" usage. The
workaround is to start off with  x<-list()  instead.

Cc'ed to r-bugs (Congratulations, that makes PR#100, I believe...)
