Here you need to remember the point of a open source project: if there
is someone who wants it implemented then he/she can implement it. This
was the case here: Some community member stepped up and started to
implement anonymous methods, but then either his time or his motivation
Please note that it was the same with me: I wanted to see class helpers
implemented which I did. And now see where I am: I'm the one who mainly
works on generics (and helper types) and have also revived a platform
thought lost forever...

I personally don't consider this a missing feature (after all delegation
itself works already), but more a bug...

Most of the features should not influence you. Only affecting changes
might be the extended RTTI (increase in executable size if enabled - and
for the RTL units it might need to be enabled) and if the switch from
AnsiString to UnicodeString should come...
