    Can you save a character by using && instead of and?

    A Monk aims to give answers to those who have none, and to learn from those who know more.

      perl -E'$y=2013;$c+=$y=~$_ for 0..9;say$c' perl -E'$y=2013;say~~map$y=~$_,0..9'

      Yup, just answered my own question and got a birdie
      perl -E '$y=2013;$y=~/$_/&&$c++for 0..9;say$c'
