Is there a simple way to to do this?

enum A{
a1,
a2
}

void fun(A a){...}
void test(){
 fun(A.a1); //works
 fun(a1); //I'd like a1 to work, but just where an A is expected to avoid
polluting namespace.
}

The magic of with statements!

enum A {
 	a1,
	a2
}

void func(A a){}
void main(){
	func(A.a1);
	with(A) {
		func(a1);
	}
}

And if you want to be *really* concise:

with (A) fun(a1);

Thanks, I know with statement could be used but I was hoping for a solution not involving adding syntax to call site.

void fun(with(A){A a}, int b){...} //conceptually like this
void test(){
 int a1=1;
 fun(A.a1, a1); // would work
 fun(a1, a1);    // would work
}

If you control the declaration of the enum, you could write:

alias a1 = A.a1;
alias a2 = A.a2;

A bit tedious, but it works, and could be automated if need be.

yes, but that pollutes the scope, what I wanted was to only expose the aliases in places where A is expected, see motivational in previous message:

void fun(with(A){A a}, int b){...} //conceptually like this
void test(){
 int a1=1;
 fun(A.a1, a1);
 fun(a1, a1);    // first a1 refers to A.a1, second one to local variable
int a1
}

ok I guess this isn't possible using current semantics.
