in reply to Re^2: strange usage of s///
in thread strange usage of s/// [solved: Perl 5.14 and 5.16 bug]

#!perl -pl s/@{[s".."."gr]}\K$"//

I understand the regex like this:

s/....\K // (with the good number of '.')

...but in facts it works like this:

s/....\K/ /

I don't understand why. The usage of $" seems magic too...
