Try this:

echo hello: world | perl -lne '$aref =3D [ split(/:/, $_) ]; print =
$aref'

[] synthax gives a ref to the array returned by split()

HTH,

Objet : Forcing array context

How can I force array context ...=20
like

# echo hello: world | perl -lne '$aref =3D split(/:/, $_); print $aref'

but thatz giving the length of the array ... I want $aref to be a
reference ...
How is that possible ??

A workaround is to use the following

# echo hello: world | perl -lne '@ar =3D split(/:/, $_); $aref =3D =
\@ar;'

But I'm not satisfied with that as I've to use an extra variable @ar ...
:(

Any help ...
