Alias is just a nickname for a symbol (i.e. alias string =
immutable(char)[];) and lets you refer to that symbol with the
nickname. You can't supply runtime parameters (like constructor
parameters), but you can give compile-time template parameters
(as the result of applying those parameters is a symbol rather
than a value). Macros on the other hand, do a textual
replacement, i.e. they alter the source code that goes into the
compiler.
Depending on how brief you want to make your code, you can either
use classic inheritance
class IndexInvalidException : Exception
{
this()
{
super("The index is invalid")
}
}
or, closest as you can get to macros:
enum throwNewIndexInvalidException = `throw new Exception("The
index is invalid");`;
void main()
{
mixin(throwNewIndexInvalidException);
}
String mixins transform a string into an expression, and paste
the expression wherever it is mixed in. It gets precompiled
rather than substituted in the source code. This means it's best
to have the whole line into a string, instead of individual parts
(you can't have a mixin with just `Exception("The index is
invalid")` for example).

There's nothing exactly equivalent to the C preprocessor. The
closest you'd be able to get without using a keyword like mixin
is to use a function:
```
Exception invalidIndexException() { throw new Exception("Index is
invalid"); }
if(false) invalidIndexException;
```
Of course, you can also subclass Exception:
```
class InvalidIndexException : Exception
{
this(string file = __FILE__, size_t line = __LINE__)
{
super("Index is invalid", file, line);
}
}
if(false) throw new InvalidIndexException;
```

Because you need two different versions to choose between them, either
set a per module version or use static if with enum's.

No idea. But it's probably the only way of actually using them right
