[fpc-pascal] A better way?

[Tony Whyman]

Just remembered, FPC also supports macros - see 
http://www.freepascal.org/docs-html/prog/progse5.html

I haven't tested it, but you should be able to do

{$MACRO On}

{$DEFINE aClassBObject:=TClassB(FClassBObject) }

and then use aClassBObject instead of the coercion.
