It does work well, but there's one more issue: the type of octal!x is 
always ulong. To make the code industrial strength, you should observe 
the usual D rules:

* if it fits in an int it has type int, otherwise it has type long

* the suffixes U, u, and L should be observed

If you make these changes I'll commit your code in std.conv with credit.
