Thank you very much, for your replies. I think noe I maybe understand the
problem a lot better.
1. Yes I wanted to avoid type switches, escpacially in different modules.
2. "myType" ist a placeholder for a complext struct, and the comparison
operators are only the basics. The goal are "contain" ans similar
operations on these structs. And i would have prefered to provide only a
carfully designed "less" operation and not repeating code.
3. Lessons learned: First i thought the "sort" package don't have this
problem. But you are right: They avoided it. The only solution can be, not
to define the operation ("less"), instead defining a metric for this
operation (at the sort packege it is "len()"). So you can do everything
with simple types and not with a placeholder which should be "compare" and
"interface{}" at the same time.
I hope my conclusion is basicly right,
ty, c.
