Same interface and functionality is priority of the library. But it's not that easy. It depends on many low level compiler details. In few cases fully compatibility is impossible. You can check how compatible it is: https://github.com/dathox/generics.collections/raw/master/GenericsCompatibilityMatrix.pdf Extensions are possible, but they should be put in separate units so that if Delphi extends its unit later in a different way, you can't get conflicts.

Veteran Pascal programmer here...
I haven't really started using it yet, but I read through the whole Oxygene
documentation the other day. (Didn't take long ;-) )
The Oxygene dialect is absolutely beautiful in my opinion. Lots of things
in there that I've been wanting for decades and many stupid things dropped
completely. Silly example: var declarations when you need them like C.
Practical example: parallel programming built into the language as opposed
to Delphi XE7/8's really ugly solutions with their parallel library. (I
can go on with examples with the OP's permission).
I agree with the OP that the Delphi language had become uglier and uglier.
I want a programming language that looks good when I write it. This is why
I am still using Object Pascal and not Java or C#. If FPC's only goal is
Delphi compatibility, then perhaps I won't be on this list anymore some
years from now.
The world is looking for a new language. That is why we recently got
Google's Go and Apple's Swift. I believe a modern and clean dialect of
Object Pascal has a leg-up on both of these.
Now, this is related but OT: CPU-native compilation is becoming outdated
just like Assembly programming did. I always used to _hate_ .NET and Java,
but using a platform's own stack must surely be the future. Example: Delphi
XE8 cannot produce a binary for Android on Intel Atom. With Java you would
never have encountered this problem. (There are a lot of tablets currently
being produced with Atom processors).
So will FPC embrace the future? Or is the project only geared toward
veteran pascal programmers that don't share my vision?

Paul van Helden.

More 2009-XE2 compatibility level is minimum (best times for Delphi language when Barry Kelly was on the Embarcadero board). This is start point, and solid base to introducing new important improvements (with small exception for example for TValue from RTTI module - to perform best performance on all platforms without hacks I need to finish small MODESWITCH).
