27	Eq instance is not compatible with Monoid instance for Picture	Chris Smith		The Monoid instance for Picture obeys neither the identity nor associativity laws when equality is determined by the Eq instance.  This could be fixed by either: (a) adding special cases for Blank and Pictures as top-level constructors in the Monoid instance, or (b) flattening the nesting structure implicitly during comparison in the Eq instance.	defect	new	normal		Unknown	1.5.0
