THANKS, this looks even cleaner :)

Nice! Yeah, I was sloppy in my newsgroup coding, sorry.
One minor nit here, the to!(dchar[])(word.dup), the dup is not necessary, you are going to end up allocating a temporary array and throwing it away.
Just do word.to!(dchar[]). `to` takes care of all the formalities.

THANK YOU for all the great hints and explanations here and in general in this NG, Steve!
No blaming for the "sloopy code" at all. I should have seen the missing [] by myself, but...
_AND_ btw. your hint with the "release" was key to the discussion / solution anyhow! :)
