Looking at this code block from a lazy programmer's perspective, if Go supported generics, we'd have to type two extra characters, < and >.

It looks like the biggest feature of generic code support has just been neutralized. When we consider this information along with the functions we get for free with gen and the fact that the performance hit is guaranteed to occur at compile time (rather than runtime), it makes Go's direct support of generics seem like a benefit ...
