is there any reason to allow

BasicType AnonymousDeclarator = AssignExpression

as a parameter? As far as I know, it's gibberish (but, then, I don't 
know very far).

I don't understand your question. Are you suggesting that something be added

for example:

int myfun(int=10);

 for example:
 
 int myfun(int=10);
 


Theory 1: it's a side effect of two features:

this is allowed

int myFunc(int)  // I never use the arg so why name it?
{
}

and this is allowed

int myFunc(int i = 5)  // normal defaulting
{
}

so to avoid corner cases they are allowed in combination

theory 2:

it gives a function (with an anon arg, see above) that can be called like 
this:

myfun(5);

and like this:

myfun();

To elaborate, this would be useful for extern functions, i.e.

extern(C) int myFunc(int = 5);
myFunc();  // Calls myFunc(5);
myFunc(6);

Ah, and yet another use. I think that is an even better theory than either 
of mine.
