My brain hurts.
A class field is just a pointer. Since classes are not reference
counted, nothing special is done for record fields which are classes.
This will cause issues with a Fillchar for the class, or not?
No.
The idea is.. I want to create/ponder about a "standardized" way to
init ANY sort of record because a lot of silly bugs in pascal are
because of these uninitialized local scope records, or similar non
initialized things.
If you have local record which was declared but not yet used, a simple
fillchar(rec,sizeof(rec),0) will set everything to 0/nil/empty. If it
may have been used earlier and contains refcounted fields, you first
have to call finalize(rec).
Or you can let the compiler decide whether or not finalize() is
required by using a wrapper with an out-parameter like the blog guy did.
