Here's a new one:
#import <flx.flxh>
typeclass Show2[T] {
virtual fun str2: T -> string;
virtual fun repr2 (t:T) : string => str2 t;
}
instance Show2[bool] {
fun str2 (x:bool) => "foo";
}
open Show2[bool];
print $ "repr: " + (repr2 true); endl;
Errors out with:
> ./flx -I. --force --inline=0 foo2.flx
CLIENT ERROR
Virtual call of 5115 dispatches to 5130
In foo2.flx: line 5, cols 11 to 45
