Re: Doubt about compiler error of `has_value` with arrays

Hi Marcos!

If you're using hilfe, you may occasionally notice that perfectly legal 
code doesn't work. That's a result of the "magic" that makes incremental 
compilation and evaluation in hilfe possible. I think this is one of 
those occasions. I'm sure that someone with understanding of how hilfe 
works under the covers can provide more details, or possibly a fix.

In the meantime, you can get around this error by using the following:

> int x;
> array y = ({ 1, 2, 3, 4 });
> x = has_value(y, 5);
(2) Result: 0

Hope this helps.

Best,

Bill
