Re: implicits and breeze, I don't know why you think it's a problem.
Implicits are a compile time feature and combined with value classes, there is
zero runtime overhead. Or is there something else you are referring to?
Re: LGPL, I don't know any OSS friendly companies that would avoid it (and
I contract with all the big boys). The licensing is a pissing contest between
Apache and FSF. LGPL gives the original developers much more power than the
Apache suite.
