Münchausen numbers

A Münchausen number is a number equal to the sum of its digits raised to each digit's power.

For instance, 3435 is a Münchausen number because 3³+4⁴+3³+5⁵ = 3435.

0⁰ is not well-defined, thus we'll consider 0⁰=0.

Write a program that finds all the Münchausen numbers. We know that the largest Münchausen number is less than 440 million.
