```d
import std;
struct tree(T){
	alias node=typeof(this)[2]*;
	SumType!(T,node) data;
	bool isleaf()=>
		data.match!(
			(T)=>true,
			(node)=>false);
}
unittest{
	tree!int foo;
}
```

adding names to the lamdas arguments cause it to compile

This is expected behavior.

Those lambdas are templates, adding names stops that.
