This produces a confusing error:

<ZoffixW> m: class Foo is Int{}
<camelia> rakudo-moar 42a583: OUTPUT«===SORRY!=== Error while compiling 
/tmp/poMXu0zSBD␤Cannot call trait_mod:<is>(Foo, Int, Hash); none of these 
signatures match:␤    (Mu:U $child, Mu:U $parent)␤    (Mu:U $child, 
:$DEPRECATED!)␤    (Mu:U $type, :$rw!)␤    (Mu:U $type, :$nativ…»

Perhaps, the same thing that's done for subs can be extended for classes too:
<ZoffixW> m: sub foo is export{}
<camelia> rakudo-moar 42a583: OUTPUT«===SORRY!===␤Trait 'is export' needs 
whitespace before block␤at /tmp/5tO_UVrVAD:1␤------> sub foo is 
export{}⏏<EOL>␤Missing block (apparently claimed by 'is export')␤at 
/tmp/5tO_UVrVAD:1␤------> sub foo is export{}⏏<EOL>…»
<TimToady> maybe that's what we're thinking of
