The biggest issue with stenciling is lack of inlining. So for example if the argument to a generic function is an array backed container, then element access will have to go through a method call that cannot be inlined.
Besides the call indirection, the compiler also loses optimization opportunities.
With the stenciling design many generic functions found in the C++ stl have to pay significant abstraction costs.

Anyway, I like the go design.
