One thing that i did not like about FPC Generics is the impossibility of
doing something like this :
Type
generic TList<_T>=class(TObject)
type public
TCompareFunc = function(const Item1, Item2: _T): Integer;
var public
data : _T;
procedure Add(item: _T);

Yes, but the semantics of discriminants is slightly different than in PASCAL.

This usually comes when you compiled your Apache module with the wrong
version of httpdXX directory from fpc/packages/.
There are 3 included in fpc:
httpd13
httpd20
and

I don't know, but ADA reportedly does.
I don't know the differences to Pascal. Does it have the same syntax for
variant records?
Such a feature definitely seems useful to me.
Of course it would b
Given that the OP was asking about learning, maybe it would be worth
mentioning that the way we normally have "data structures which hold
different data" these days is by polymorphism in objects or classes.

I have to admit. After working for so long with RDBMS API's, I got
quite rusty with the more low level file reading, record structures
and pointer arithmetic. Database desktop applications clearly

This should not cause as RAV. You must call
SetLength(toarray,SizeOfMemory) and also don't use SizeOf(tocarray)
use Length(tocarray)*SizeOf(What ever the element is))
