Hi,

I'm new to Ada and have a questions on polymorphism. The standard
way to have polymorphism in Ada are tagged records. But for my needs
this requires too much space. List cells would have a size of 3 words
instead of 2. I'd also have to put integers in records. This would
require too much time and space. I'd like to convert access values to
integers and do my own tagging. I could simply translate my C code.
But it would be nice to see how an experienced Ada programmer would do
this in Ada. Can I find some code that does this somewhere ? 

Thanks
