I openly *hate* the attribute syntax. It's just not Pascal and simply 
copied from their .Net compiler, because hey, other .Net compilers do 
that just like that... -.-

Also considering that the trunk compiler currently does not have support 
for attributes (let's put aside that branch for now) it is definitely 
easier to add a new keyword, because the compiler is built in a way to 
allow the easy addition of new keywords. Additionally using attributes 
would mean that one would need to add detection for special attributes. 
And that's more annoying stuff then a keyword is. Additionally this can 
be added more safely to other modes (e.g. macpas, which supports classes 
as well) than the attributes can.
