British NVC community CG10
NVC community CG10 (Festuca ovina - Agrostis capillaris - Thymus praecox grassland) is one of the calcicolous grassland communities in the British National Vegetation Classification system. Of the upland group of calcicolous grasslands, it is the only one with a short sward associated with heavy grazing.
It is a comparatively widely distributed community in the British uplands. There are three subcommunities.

gollark: 6 (partly cultural). User/implementer divide. Only the people who write the standard library get to use generics, `recover`, etc. And no.user type can get make, new, channel syntax, generics.
gollark: 1. Lack of generics mean that you can either pick abstraction or type safety. Not a nice choice to have to make.2. The language is horrendously verbose and discourages abstraction.3. Weird special cases - make, new, some stuff having generics, channel syntax4. It's not new. They just basically took C, added a garbage collector and concurrency, and called it amazing.5. Horrible dependency management with GOPATH though they are fixing that.
gollark: <@301092081827577866> I have reasons for bashing Go. Several reasons.
gollark: It is?
