procedure InitRecord(out R; SizeOfRecord: Integer);
FillChar(R, SizeOfRecord, #0);
Even if it has dynamic array, ansistrings, shortstrings, integers,
I assume it is okay to initialize it this way (assumptions are bad).
The problem: initializing records with automated types by going through
each and every field is error prone because if you expand the record
later on with more fields, you might forget to update your custom init
And a question: does old borland style "object" initialize anything as
classes do? Stack based ones? heap ones?
Interesting pondering: what would be nicee is an auto initialized record:
var something: somerec autoinit;
Many times I find myself initializing stuff tediously and error prone
when you do it a human way without automation.
