Leave it as a general "reference" (rval). It can be a direct reference
to a variable, constant, class member or property, or a function
call. I'd leave the code creation for such a reference to the
optimizer, which could replace function calls with inline code; at
least I'd appreciate if some of the stupid forwarders or procedural
replacements for C preprocessor macros would result in inline code in
optimized Pascal programs.
