Thank you it works like a charm.
I also found out that .toString works.
I should have been able to find toString immediately, but .get!T 
I probably never have found myself. Can you tell which one is 
best?
And the type `VariantN!32LU` why? It looks very odd to me.

I have tried to learn D a couple of times before, but always 
given up on odd things like `VariantN!32LU`. This time I try a 
bit harder. I do not learn well by books, courses or videos. I 
learn by solving a small problem I have and then expand. My 
intention is to build a compiler or an OS just for fun, or a 
world class SAP connector. Right now I am too busy with life and 
$work, the latter will end this year giving me more time for 
programming. I hope D will work for me. Again thanks for good and 
fast help.
