In D I think "body" actually is redundant since in/out always 
should be followed by a function body?

Maybe it has more to do with parsing strategies. If you use a 
separate and fully independent lexer then the symbol "body" might 
be lost and replaced by a keyword enumeration so by tradition you 
reserve all keywords?
