Solving the problem is demonstrated by the documentation.
Your argument is really very poor. Here is an example of how poor it is: on page 153 of the FPC reference guide, there is a "precedence of operators" table which, unsurprisingly, includes the Boolean operators. In spite of that being clearly documented there, you made some assertions about them in another thread that are clearly incorrect.
Not only are Boolean operators precedence clearly documented, I believe that anyone with the credential you, at least implicitly claim to have, would already know.
Even someone who has read the manuals cannot be expected to remember every single detail, particularly when such details are dependent on how a compiler is implemented. This is in stark contrast with Boolean operators precedence which are, very likely, implemented the same way by every compiler. IOW, something that is really hard to "forget".
The bug is that people ask first and then read.
There is bug that is worse than the above, specifically, people who make incorrect authoritative statements, support such statements with dubious credentials and, seem to be unable to ever acknowledge their mistake. If you need an example of that, read your own posts in this thread.
