Does that make sense? I’d like to scratch the idea of default properties and do
this instead if it was permitted.
No. FPC is not going down that operator madness.
So why are default properties better? I thought the compiler team would like
the idea of . overloads because it’s so much less intrusive on the compiler and
more predictable for the user. Please explain your reasoning if you don’t mind.
Because I don't want to open the can of worms that is going to be
overloading the postfix "operator". People are going to abuse the hell
out of it (they will with default properties as well, don't get me wrong
there), making the language much harder to read. Nowadays you can rely
on the "." denoting some sub element. With operator overload using a "."
could mean triggering some credit card payment (I'm exaggerating here,
but this would technically be possible).
Default field properties extend a mechanism that already exists and also
have a much narrower scope of possibilities for abuse.

Sven
