It's fairly straightforward for an obfu. Maybe if you used some special variables, some less-than-obvious logic and a handful of unexpected delimiters it would really mess with some heads. Just a quick reincarnation of your code...
#!perl $;=q;a;and$;=~s q\n qq;$,.=$;++x3 .q; ; for 1..7;@_=split q ; ;,$,;@,=(66___22, 12_154=>8559=>1_052 ,345,1219,2663,4746 );@_=split(q,,,join q,,,map{$;=$_;map$_ [$;]++,1..$,[$_];$_ [$_]}(0..6))and+die "@{[map{$_= ucfirst join q,,,splice@_,0 ,$_}split+q,,,$,[7] ]}",chr(ord(+$/)),,

"Argument is futile - you will be ignorralated!"
