Hi Ryan,
It's possible. Just change your declaration of `c`:
var c: TBase;

Of course, you're only going to have access to methods that are declared in
TBase.
You can also approach this sort of thing with interfaces...

Hey Craig,
I've been experimenting with anonymous functions in FPC and have working
code, but they're not at all like what Delphi provides:

(On the other hand, they require 0 compiler changes...)
I asked about lambdas in

So...
The top google result for "free pascal TComponent" is:

I don't know if this would be useful to you, but I've been working on a

For what its worth, I use free pascal practically every day, but rarely
open Lazarus.

Hey all,
I was experimenting with using some of FPC's features together and came up
with this:

Basically, it's just a generic implementation of the Observer design
