Sure, I wanted to ask about the Go tool anyway. Some of the behaviour was 
finalised quite late on and because it's not in the spec I wanted to know if 
the current behaviour with regards to $GOROOT being prioritised over $GOPATH 
was going to be guaranteed going forward.

I rather suspect we will have to move the install location for third party 
libs anyway. According to the plans for Go 1.1 in the last comment of this 
issue:

Sounds like a plan... 

Go-OpenGL might need looked at. There was some talk this week on the go-nuts 
list of difficulties using this since Go 1. I didn't follow the thread too 
closely but the reporters might not have realised use of Go-OpenGL needs to 
used with runtime.GOMAXPROCS(1) or the goroutine that invokes the GLContext 
needs to be locked to the OS thread.

We should probably review and assertain the state of development of current DB 
drivers as well. There are CGO wrappers for C implmentations and native 
drivers. In general the CGO drivers seem to be the older ones (but not 
necessarily the ones with most features or the most mature). The native SQL 
drivers now finnaly seem to be coalescing round the database/sql and 
database/sql/driver std library API. There are also a bunch of different NoSQL 
drivers to evaluate.

There are competing drivers for MySQL, Postgres, Sqlite3, Oracle, Redis, 
MongoDB, CouchDB, Kyoto Cabinet and Riak. I doubt I'll be able to evaluate 
even half of these but I'm pretty sure some of the competing implementations 
are bit-rotting already.

This is one area where we could certainly use an extra pair of hands ;)


Cheers the noo,
