Feature. http://www.digitalmars.com/d/2.0/pragma.html:

"Pragmas can be used by themselves terminated with a ';', they can
influence a statement, a block of statements, a declaration, or a block
of declarations."

E.g. pragma( blah, blablableh ) struct foo {}; might mean something,
and in this case the pragma would modify foo.

Heh, should've DAFS, thanks.
It's still baffling a bit - what can pragma(msg) possibly influence? Perhaps
there should be a 
division - influencing vs. statement flavor. The compiler could disallow usage
not lying in a 
particular pragma's nature.

The parser doesn't know about what "msg" means. To do this you'll have
to define each pragma as part of the syntax (you can't, since most of
the usefulness of pragma is language extension) or have a stmpragma and
exppragma to parse differently "statement flavor" and "influencing"
pragmas, or something like that.
