OpenEuphoria

I'm writing an application that has multiple digital filters. Calling the filter:

• Calculates a filtered result, and
• Updates the filter's history.

That is, two different things are being modified here - there's a result returned from the function call, and as a side-effect, a data structure gets updated.

But it raises the question: why do I have to jump through these hoops at all? Why can't OpenEuphoria let me pass values by reference like just about any other language?
