Err.. let me tell you what will happen if i, say, add an instance
variable to some basic class -
it will recompile all subclasses. And when some of those methods could
contain underscores as assignment,
while some of them (a newer ones) could use underscores in
No matter what you choose in a system-wide preference, you won't be
able to recompile the all classes.
Will Shout be able to help me with that? :)
It is obvious, that to prevent this from happening, all sources, which
is going to the compiler, should
use same syntax, or each class should have own #useUnderscores setting.
But that wouldn't help, if i add an instance variable with underscore
in base class,
while subclass will still insist on using underscores for assignment -
then it will be unable to access that ivar
in own methods :)

Well, my first question was 'i can?'. It appeared that i can't (but i
will try your fixes).
Also, how you suppose to deal with the above (recompiling a base class)?
