		microtonal on April 27, 2014 \| parent \| context \| favorite \| on: Go's power is in emergent behavior If you don't have parametric polymorphism, you only have two options to implement new containers: a new implementation for each type or using interface{}. The first leads to a lot of duplicate code, the latter requires you to use introspection to use safely. So, it does happen a lot, or you are making duplicate code.

Or you just don't need polymorphic containers that often (other than the ones that go already gives you).
