Re^2: The Backslash Challenge

Nice trick!

Interestingly, it doesn't work for me. In the debugger, I'm getting

  cont:
Can't find string terminator "\" anywhere before EOF at (eval 13)[/usr
+/lib/perl5/5.26.1/perl5db.pl:738] line 2.
 at (eval 13)[/usr/lib/perl5/5.26.1/perl5db.pl:738] line 2.
    eval '' called at /usr/lib/perl5/5.26.1/perl5db.pl line 738
    DB::eval called at /usr/lib/perl5/5.26.1/perl5db.pl line 3140
    DB::DB called at -e line 1

And if I run it in a script instead, the output is _, not \ :-o

map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]

> cont: A backslash at EOL marks a multiline statement in DB. I had a trailing whitespaces to avoid this, but the C&P from cmd.exe erased them. :( Fixed now! > And if I run it in a script instead, the output is _, not \ :-o both lines? lemme check... ... Argh! Seems that the context of the debugger is initializing a "crucial thing" which can't be taken for granted :( <Reveal this spoiler or all in this thread> update yes a `use DB;` at the start of the script is "fixing" it. Actually that could be a source of a Heisenbug. Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery}	[reply] [d/l]
