i still don't get what you expect @$_ to be? explain it in english if
you can. it looks like a symref. if it is meant to be an array ref then
you should initialize @a with ([]) x 5. and i don't think there is any
difference in the semantics of a for loop vs. statement modifier in this
case. you just never had a proper array ref in $_.

and your comment about any value will be overwritten makes no sense
either. it has to be array refs for @$_ to have any meaning other than
symref.

sorry to keep trashing you john, but you are really missing the target
on this one. just loop with 0 .. 4 and build the whole damn thing
instead of having something built half assed.

BTW why does this list seem very slow? my posts seem to take a long time
to get back to me. is it a slow fetchmail pol cycle or a slow mail host?
