Very nice!

The OP has told me via e-mail that he really wants Java, of course.
So unfortunately the 'eval big_long_string' trick that I think is
at the root of EyeDrops' approach wouldn't work.

Out of curiosity: Why *two* nested 'eval's at the start of this program?
And what does ('['^'.') mean?  0x5B^0x2E = 0x75 = 'u', or is there some
deeper magic at work here? :)
