Ok, advanced records in 2.6.0 are it seems buggy as hell (with optimizations on), so I'm searching for an alternative. For the simple case objects work quite well, but for generics I have a problem.This is part of the code: generic TGVector3<T> = packed record {... types} public class function Create( aX : T = 0; aY : T = 0; aZ : T = 0 ) : TGVector3; static; {... functions} class operator +( const A, B : TGVec3 ) : TGVector3; {... other operators} class operator Explicit( const A : array of T ) : TGVector3; {... properties etc} end; The generic record has a lot of utility functions and operators, and is used in specializations for Single, Double, Integer, Byte and one custom type, so rewriting it as not-generic is out of the question. Now, I'd really like to convert it to an object, but objects do not support built-in operators (or do they?). Any ideas how to circumvent that?
Even if objects would support operator overloads this would not solve your problem. The above operator overloads simply won't work with generics in 2.6.0. I'm working on the issue in 2.7.1, but it's not completely trivial. And no, a merge to 2.6.1 is - in my opinion - out of the question, because the changes in the implementation of generics between 2.6.0 and 2.7.1 are very massive (and they get more the more bugs I fix).
[Though this bugfix might even have a chance of being mergeable, but I won't make any promises that it will be the case in the end]
