Re^3: simplifying substitution

Without the /x modifier, a space should match literally. What's the output of

perl -lwe 'print qq( $]) =~ s/ /v/r'
[download]

(use double quotes instead on MSWin)

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

I get this output from that command (I'm not on Windows): `Bareword found where operator expected at -e line 1, near "s/ /v/r" Unquoted string "r" may clash with future reserved word at -e line 1. Can't modify string in substitution (s///) at -e line 1, near "s/ /v/r " syntax error at -e line 1, near "s/ /v/r " Execution of -e aborted due to compilation errors.` [download] When I check the version, I get this: `perl -v This is perl 5, version 12, subversion 4 (v5.12.4) built for darwin-th +read-multi-2level (with 2 registered patches, see perl -V for more detail) Copyright 1987-2010, Larry Wall` [download] Blessings, ~Polyglot~	[reply] [d/l] [select]

OK, 5.12 doesn't have /r. So what about `perl -lwe '$v = qq( $]); $v =~ s/ /v/; print $v'` [download] `map{substr$_->[0],$_->[1]\|\|0,1}[\\|\|{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^ARGV,3]`	[reply] [d/l] [select]
