Sounds like Alsys. :-)

The LRM (13.5) specifies the part after the "at" must be a "simple 
expression". A static expression would certainly qualify as a simple
expression, but so would a function call (LRM 4.4). I'm not sure how
kosher it is to make your compiler MORE restrictive than the language
specifies. Perhaps one of the compiler folk here can comment on this
one. But it sounds like you have a case to me.
