There it is again: my pet project: Why doesn't pascal allow circular unit references (at least for classes, like forwards)!
I like pascal very much but this is the biggest annoyance!
You always have to work around this (put multiple classes in one unit, create interface classes, ...). And now this:

I have such cycles, but it worked before.
I removed this cycles and it worked as expected.

Isn't there a way to force the order?

Why isn't it initialized first even if the unit is the first after Forms in the program?

If there are uses-cycles via the implementation section why doesn't
fpc prioritize interface order?
