Re^2: Displaying bit-vectors with Most Significant Bits to the left?

Using reverse on a single value in list context is a no-op.

You posted untested code in a fake demo.

So clever!

  DB<315> undef $m1; vec($m1,$_,1)=1 for 0,2,8,9,10

  DB<316> x unpack 'b16',$m1
0  1010000011100000
  DB<317> p reverse unpack 'b16',$m1
1010000011100000
  DB<318> p scalar reverse unpack 'b16',$m1
0000011100000101
  DB<319>

You posted untested code in a fake demo. So clever! Thanks for calling me a fool. So nice! `p scalar reverse unpack 'b16',$m1` [download] Yeah, the `scalar` was missing, which you spotted and corrected. So what? perl -le'print map{pack c,($-++?1:13)+ord}split//,ESEL'	[reply] [d/l] [select]

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',$m0 result: '0000011100000101'` [download] So not only am I a fool, but a dishonest person also, a liar and a faker, whose code is not to be trusted. At all! update: No Sir, I did not pretend to show tested code, as you claim after having edited your answer (without note). I did, and you can beat me to death for that, forget the `scalar`. Next. perl -le'print map{pack c,($-++?1:13)+ord}split//,ESEL'	[reply] [d/l] [select]
