The data is zeroed out after being destroyed. This is to make debugging easier
in case your code might try to access an already destroyed object. In case

assumptions about the order at which the destructors are called. If you have
interdependencies between destructors for different data members, you will
set { self->foo = ARG; };

general rule of thumb is that all of these start with three underscores. There
is one, "parent_class" which doesn't because it's intended for use in your

is done to avoid conflicts with the aliases. Thus you can define the method
as "_name", if "name" happens to be some standard library function. This is
the same as defining it as "name" except that the local alias will be "_name"
without the type prefix. Gob will automatically try to extract these and
translate to full names and put them in the output source file. An example
would be:

+The lexer does not actually parse the C code, so I'm sure that some corner
cases or maybe even some not so corner cases of C syntax might confuse gob
completely. If you find any, send me the source that makes it go gaga and I'll
try to make the lexer try to handle it properly, but no promises.
Comments will not get through to the generated files unless inside C code.
This makes using something like gtk-doc harder. However I'm planning to
fix this somehow.

+The short name aliases are actually implemented as pointers to functions. Thus
