[isabelle] Locales: Interpretation changes behaviour of locale expression
I ran into the following unexpected behaviour with locales:
locale A begin
definition "name â True"
interpretation foo!: A by (unfold_locales) (* If this line is
removed, everything works as expected. *)
locale B = A +
assumes "name" (* Name is a FREE VARIABLE here*)
When defining locale B, I would have expected "name" to reference to the
definition in A. However, if there is an interpretation of A before,
"name" is a free variable in the definition of B, and I have no idea how
to access "name" from A?
1. Is this the correct behaviour?
2. How to correctly reference "name" from A, in the definition of B?
