    My best was 59 characters: 
    sub p {
map{$_[$_]+=$_[$_+1]for 0..$#_;@_=(1,@_);print"@_\n"}1..pop
}

    However, I can reduce japhy's solution from 56 to 45 characters: 
    sub p {
@_=(1,map$_[-2]+pop,@_),print"@_\n"for 1..pop 
}

    BTW, I find it amusing that monks are giving their golf subroutines one-letter names, when the subroutine name isn't counted in the length of the solution. :)

    I was considering sub pascal's_triangle {} for this one. ;)
