Welcome here and to D then.

D gives you the freedom, if you want, to put single classes in files, but the normal D idiom is to put related classes in a single module (if they aren't too much long).
And keep in mind that in D there are also free functions (and templates, inner functions, true closures, etc), so you don't need to use classes for everything.

You can also write:
public import red.xml.xmldocument,

There are several already written programs to do that :-) For example I use 'bud', there is also rdmd built in the distribution.
