Hey Christer,

try [1,2,[3]].flatten.to_s

it solves this one:
assert [1,2,3], [1,2,[3]].flatten
and probably is the easiest solution :)

however - assert not only compares and checks strings - you can use it for =
all=20
other Objects as well... so "123", [1,2,[3]].to_s looks to me not that=20
obvious - but i don't know your approach and what this array should do -=20
sending out this advice and waiting for the pros to comment your post ^^

MfG
