Not for long :)

Well, Boo was already described as a mix of VB.NET and C# by some.
We need a different parser in any case. Just by integrating this new
parser into the boo pipeline would get us a long way. In fact Daniel
Grunwald integrated the #develop VB.NET parser into boo some time ago
so it's possible to write some kind of VB code already with boo. The
semantic differences were not implemented but that would be the same
work for boo or gmcs with one nice difference: we would be sharing

Boo architecture is open enough so you can plug different parsers,
different type system rules, overloading resolution schemes and such.
Don't get me wrong it would still take a lot of work to get that
openess to a point where we will say: beatiful! But collaboration can
certainly gets us there and it looks like a fun ride from where I

Forking is generally a dead-end for code sharing. That's what happened
to mbas. That's what will eventually happen to mbas2 I guess. At some
point the two versions just diverge so much that the gap just gets too
What will it be, the blue pill or the red pill? :)
