Hi experts,

	Where in the draft standard, if any, says one can use (in the
class declaration),

friend inline void a(A&);

but not

inline friend void a(A&);

? I have been discussing with a compiler engineer who somehow seems to
think the above is true and makes the latter illegal. I cannot find any
place in the draft that says I cannot use the latter syntax. However, I
noticed that libg++ has changed "inline friend" to "friend inline" in its 
String class.
	Thank you for your help.
		Nobu

Nowhere that I can see.

The keyword `friend' occurs as part of the decl-specifier-seq.  This
is an unordered sequence of keywords and typenames.  As far as I can
tell, even

	const char inline unsigned friend * f() ;

is be legal.  (Just because you can do it doesn't mean you
should:-).

In general, I think that good coding practice would impose a
systematic order of some sort, but the importance is consistency, not
the actual order.  (My own preference is: storage-class/typedef/friend
inline virtual/explicit type-specifier cv_qualifiers.  Withing the
type-specifier, I would generally place signed/unsigned first, and
short or long before int or double.  This preference is at least
partially historically conditioned, though.  It corresponds to what I
saw in the first C code I read.)
