Well, you faked a copy from an actual test.

Think about it.

What should I think?it mimicked the REPL you are using. I did even fake the sequence number! D'oh!
Mine is different, I use perlsh from Term::ReadLine::Gnu (hacked to suit my needs), and this was the actual test using it:

package main; # [498] ~ > vec($m0,$_,1)=1 for 0,2,8,9,10

result:
''
package main; # [499] ~ > scalar reverse unpack 'b16',$m0

result:
'0000011100000101'

So not only am I a fool, but a dishonest person also, a liar and a faker, whose code is not to be trusted. At all!

update: No Sir, I did not pretend to show tested code, as you claim after having edited your answer (without note). I did, and you can beat me to death for that, forget the scalar. Next.
