my mistake was to think that all variables that start with '_' are
anonymous variables. since i managed to write code for four years
without realising my mistake, i thought it might be possible that others
are also making this mistake. if so, it seemed to me to be for the best
to explain the difference between variables starting with '_' that are
one character long, and those that are longer.
to avoid sending this (superflous) explanation to the mail list i wanted
to know if this could not become part of a ''stupid mistakes to avoid''
page on trapexit.org . however, emails to bounce. the
address is erronously expanded to
sorry for the confusion.
