in reply to Golf: Embedded In Order

I'll get things started here. I don't have time for the extra credit, but this solves the first part:
sub t_in_s { ($t=pop)=~s/./$&.*/g;$_[0]=~$t } t_in_s('abcdefghijklmnopqrstuvwxyz', 'for');
Although, if $t may contain non-word characters, that becomes:
sub t_in_s { ($t=pop)=~s/./\Q$&\E.*/g;$_[0]=~$t }

    If $s or $t can contain \n, you need a /s on both matches. But your $_[0] can be replaced with pop.

    That makes your solution turn into the 36 character:

    sub t_in_s { ($t=pop)=~s/./\Q$&\E.*/gs;pop=~/$t/s }
    or 38 if you wish to add my to make it strict compliant.
      I realized later that I had the replacement in the wrong order, and I could save two characters:
      sub t_in_s { ($t=pop)=~s/./.*\Q$&/gs;pop=~/$t/s }
      So that's 34 characters.

    Should cpanminus be part of the standard Perl release?
