Hi Wes,

How about magic `$parent` variable accessed in classes which are declared
inside other classes?

Why `$parent`? I was thinking of it in case of inner classes also, I've got
some concept about it
https://brzuchalski.com/blog/inner-classes-in-php-concept
and think therre might such variable be usefull too. This concept is
similar to anonymous classes in way that both may be declared inside other
class.

Cheers,
Micha=C5=82 Brzuchalski
