I was merely indicating syntactical elements, not the use of specific 
units, variables and constants, not even the RTL as such.
So, much like $mode objfpc extends the syntax let $mode delphi restrict 
the syntax.
There is a case to make that f.e. the C style operators and the macro 
facilities belong to $mode objfpc anyway.
Or am I wrong here?
Or is there value in it?
In that case I will have a look if I can create a patch for a $mode 
strictdelphi (or whatever name is convenient).
It should merely exclude extended syntactical elements not available in 
Delphi compared to the current Delphi compatibility support.

Sorry about the location of my last post regarding this.
