It's not about implementation in the fpc parser/compiler, or syntax 
highlighter => you can implement any such thing...

But it's breaking the fundamentals of pascal, to differentiate between 
symbol and identifiers.

Obviously it acts like a symbol does, so it should be a symbol; but if 
symbol can have chars, then why can't identifiers have $+-...
If we give up this barrier, then surely the following should be valid to?
var a$b: Integer;
symbols may need to be surrounded by spaces always, since I also would 
want an identifier/variable named
var a+b : integer;

if there should be a shorthand for "a:=a mod b" => ok => but please make 
it look like pascal.
Either inc style, or symbol style. maybe use "%=" (and "::=" for div 
(first ":" =divide))

I don't say I like those, but "mod=" is just the worst I can imagine.
