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.
