A question I'm not sure has been asked is whether it would be easy to
distiquish whether a member is that of the class, of it's instance, a
local variable, or a global variable.
Imagine the following that is several functions down the file
within a
class declaration.
...
foo: func->Int{
.... couple lines in
return a+b+c+d
}
If I ever saw this line, I would remove all hair upon my noggin
barehanded! "a" could be "This a", "this a", the global var "a",
or a
local, same applies to the other variables, with which the poor
reader
would have to manually trackdown which is declared where.
I'm not really one to like forcing of a coding style (much of the
reason why I disagree with enforcing lowercase function names), but
this is something to think of.
And while no sane coder would allow such vile code to be written, it
is common knowledge that not everyone is sane. But why am I
explaining the reasoning of PERL?

In j/ooc you can't access static members without prepending "This ".
I don't think this should be enforced, but rather simply mentioned
in the
style guide ORC (which still needs to be written, btw). It
especially doesn't
make sense with constants, eg. in oos, functions inside Display
class have to
use "This VIDEO_MEMORY" instead of just "VIDEO_MEMORY". According to
the erorr
message given when you don't use "This", this was done for 'clean
code', but
in my opinion it is sometimes cleaner without "This" and the option
should be
left to the user.
See http://github.com/tsion/oos/blob/covers-and-
statics/Src/Kernel/Hal/Display.ooc
I don't believe it would make it any cleaner to pepper that code
with "This".
In fact quite the opposite.
In j/ooc, all you have to do is remove 3 lines of code that call
that
exception and it all works fine. I don't know what must be done in
rock, but it
should also be able to do unqualified member access.
if anyone else has any thoughts or arguments, I'd like to hear them.
