Interesting ! If I am correct, the docs referred to at 
<https://gitlab.com/freepascal.org/fpc/source/-/issues/38964> say

; visibility-clause:
; METHODS|PROPERTIES|FIELDS (visibility-expression)

Does that mean that the "extended RTTI" branch supports RTTI for fields ?

My understanding is that I have to explicitely specify public for class fields, otherwise the 
compiler will issue an error.

Will try that out, thanks.
