How to make a long print string to shotcut form in perl?

  print "1.readfromfile\n2.add_ex1(4,5)\n3.add_ex2(11,5)\n4.add_ex3(9,3)\n5.add_ex4(91,4)\n";

How to do it in this form:

  print "1.readfromfile\n
           2.add_ex1(4,5)\n
           3.add_ex2(11,5)\n
           4.add_ex3(9,3)\n
           5.add_ex4(91,4)\n";
2 
print "1.readfromfile\
           2.add_ex1(4,5)\
           3.add_ex2(11,5)\
           4.add_ex3(9,3)\
           5.add_ex4(91,4)\n";

This works too:

print "1.readfromfile
           2.add_ex1(4,5)
           3.add_ex2(11,5)
           4.add_ex3(9,3)
           5.add_ex4(91,4)\n";
3 
print     "1.readfromfile\n",
           "2.add_ex1(4,5)\n",
           "3.add_ex2(11,5)\n",
           "4.add_ex3(9,3)\n",
           "5.add_ex4(91,4)\n";

Done.
