Conversely, adding it before the semicolon in case of procedure/

I don't have problems with it's usage in procedures, functions or methods.
The modifier appearing after the semicolon seems like the correct syntax,
and that is how 'virtual', 'override' etc is used. This I think is correct
and should stay as is.
The issue I do have is using deprecated in a type declaration, where it
appears *before* the semicolon. This just doesn't look or feel right. It
affects variable, class and record declarations. This is what I was talking
about and think should be fixed in objfpc mode and inconsistent usage
limited to only delphi mode.
Jonas tried to explain that this is not possible.
Consider the following - what you propose - statements:
Var
A : Integer;
deprecated : Boolean;
The compiler cannot decide whether the 'deprecated' is a modifier or the
name of a variable. Both are possible (deprecated is NOT a keyword) and
valid.
With the current syntax:
Var
A : Integer deprecated;
Deprecated : Boolean;
The compiler knows in both cases what is meant.
The matter could be resolved by making 'deprecated' and all other modifiers
into keywords, but that would be a major backwards incompatibility.
Michael.
