Re: [go-nuts] [urgent] need aguments to justify use of Go for a scientific application

Not to be a buzzkill, but… Maybe not having good arguments for using Go in this case should be taken as a signal that Go isn't a good fit? As much as I think Go would be useful for scientific applications, if we want to see that happens, we should work on making Go better for them, not on making up
