This born casually when I was playing with another challenge.. and I'll be glad to see other's solutions.

The serie is described in OEIS A073015 and is formed by numbers:

      3, 4, 9, 64, 3969, 15745024, 247905749270529, 614572605213818940
+04129398784, ...

Here the constraints of the challange:

• generate the right serie, obviously
• terminate after inf is reached
• do not use any module, but pragmas and everything covered by perlrun are valid allies
• for oneliners only chars included in the quote (or doublequoted) are counted (perl -e '1' is one char)
• have fun

Comments about the serie are welcome as solutions.
