Although I respect the opinions expressed here, I think you might be
pleasantly surprised by how the proposed design would dovetail with the
rest of Go and make a number of things much more convenient than they are
at present.
It would be nice, for example, to have a full range of collection types in
the standard library without the need to use interface{}, type assertions
and the performance overhead of 'boxing'.
It's not an ugly design with angle brackets all over the place and most of
the time you'd hardly notice you were using a generic function as the type
parameter(s) would be automatically inferred from usage.
Better still it would be compatible with Go 1.
Admittedly, there's a lot of discussion over the design at present though
that's mainly about the constraint system. Everybody agrees that this needs
to be both simple and expressive though opinions differ over the best way
to achieve that.
Anyway, as I said in another thread, the important thing is that the
existing built-in generic stuff is not interfered with, so those who prefer
to avoid generics may do so and carry on as they are. That way everybody
will be happy :)
