I'm reading http://bracha.org/executableGrammars.pdf now.

I like the brevity of this strategy.

Both really.

Yes.  Where in the grand scheme of Newspeak is #become: needed.  I
don't immediately see why this is a challenge.  Does Strongtalk use a
direct-pointer model?

What's wrong with Strongtalk's #doesNotUnderstand:?

I poked around in Strongtalk-commit.  Most of the recent submissions
seem to relate to the gcc build process or to linux.  Is anyone
developing with the latest version of Visual Studio.  I just asking.
I don't really want to use it because the VS IDE seems to be broken is
basic ways, anyway.  What is the most common, least problematic C++
tool set being used to edit and build Strongtalk C++ code?

Concerning the use of Newspeak, I assume that I can download the
latest Squeak and play with Newspeak there.  I think I'm also reading
that there is a native version that Cadence are working on, but have
not released yet.  Is this correct?  Is there a firm schedule for the
release of this native version?  Is this native version being built
from the ground up, or have you decided to commit to the integration
of Strongtalk and this current native Newspeak, instead, to produce,
in less time, a faster native version.  I suppose that you will commit
to the latter path, if the above problems in Strongtalk can be fixed.
Is this correct?
