You can have multiple interfaces, and interfaces can have default
implementation for its methods.
What really prohibited is to have multiple base classes as this
will over complicate data layout and the compiler without much
benefit (if any at all).
What are semantic limitations you talking about? D is much more
expressive than C++, there is also CTFE and code generation with
mixins.
Mixins can do pretty much anything preprocessor can, except they
can't inject self-invocable code, you always need an explicit
"mixin(foo)" statement, and that's the only limitation compared
to preprocessor.
IIRC Vibe.d using them for template engine.
Also D has raw strings, just like this
https://github.com/buggins/dlangui/blob/master/examples/dmledit/src/dmledit.d#L73
Which again with mixins can be turned into DSL(domain specific
language),
with this you can write your own template that parses that string
and for example builds a widget tree out of it, like this
https://github.com/buggins/dlangui/blob/master/examples/helloworld/src/helloworld.d#L20
