ok, so i'm trying to create a here doc for a little program i'm writing and
it dosn't seem to want to work right!

this code works:
###
pry(main)> print <<NUMS
pry(main)*   08 02 22 97 38 15 00 40 00 75 04 05 07 78 52 12 50 77 91 08
pry(main)*   49 49 99 40 17 81 18 57 60 87 17 40 98 43 69 48 04 56 62 00
pry(main)* NUMS
  08 02 22 97 38 15 00 40 00 75 04 05 07 78 52 12 50 77 91 08
  49 49 99 40 17 81 18 57 60 87 17 40 98 43 69 48 04 56 62 00
=> nil
###

but this:
###
pry(main)> str = ''
=> ""
pry(main)> str <<NUMS
pry(main)*   08 02 22 97 38 15 00 40 00 75 04 05 07 78 52 12 50 77 91 08
pry(main)*   49 49 99 40 17 81 18 57 60 87 17 40 98 43 69 48 04 56 62 00
pry(main)* NUMS
###

gives me:
###
SyntaxError: (pry):43: Invalid octal digit
  08 02 22 97 38 15 00 40 00 75 04 05 07 78 52 12 50 77 91 08
    ^

`eval'
