thx for the info tim.
unfortunately i wanted to avoid any externals for this patch (i mean any
extra externals not present in the pd bundle). i guess i'm going to have
to remplace my expr with simple operators ... jeez ... i'm going to love
this .. :)

i think this $0 support would be a nice thing to add in the expr todo
list :)
