hahaha... You are asking all the questions I've been meaning to ask 
too.

From your question, just goes to show how rubbish Delphi is being
designed these days. Mixing concepts of class and record
interchangeably. And now we have "records" with constructors and
destructors! WTF. EMBT/Delphi are seriously polluting the Object Pascal
with all this rubbish. Unfortunately FPC feels like they need to follow
them like lemmings.



I don't blame FPC for following them in some respects because it enables 
compatible code to be shared between FPC and delphi, but I get what you 
mean..


Oberon is a fresh new start without all this rubbish but look where 
oberon is: no where.

Almost no one uses it, nor cares about it..

so if fpc does things right and diverges from delphi, you have 
incompatibility ...


But I see what you mean and understand your point

Moreover it doesn't add anything and it only means an extra requirement for
editing to change a record to a class and viceversa.

Records don't allow destructors, only constructors. Also they allow to more
tightly couple initialization functions for some record with the record
they belong to. Same for operators by the way: without them you couldn't
use a record's operators in generics. Also I personally prefer to have
routines that deal explicitly with a given records type as part of said
record.

Sven

It's simply that Delphi introduced static methods to records using the same
syntax as for classes and operators followed along.

We've simply followed that along as we would have needed to do so at least
for mode Delphi anyway and the implementor of advanced records decided not
to deviate from that.
