There was a problem hiding this comment.
Oops not clever enough, have to fallback to AttributeError

Description
As explained in the related issue this class is messy because it internally upcasts the values to 0d arrays, so that
shared(shared(5).get_value())belongs to a different class thanshared(5)but are exactly the same objects otherwise!This was a source of bugs in PyMC. The way you create an object shouldn't matter for type checks, only what you actually ended up creating!
There is a proper ScalarSharedVariable if someone really wants to work with scalar types
