Perl5
- I like that perl has stuff like ... - ... is more powerful than anyone could imagine
- Oneliners? In my crontab? - perl -MScript::CleanupExpiredEntries -E'Script::CleanupExpiredEntries->new_from_args->run'
- I like perls scoping - I think it's chill that perl has both lexical and dynamic scoping.
- [(a,4),(b,3),(c,2),(a,1)]
- Run-length encoding - perl -plE 's/^(.)(\1*)/$o.= $1.($2&&length" $2");""/e while $_;$_=$o'
