IntList is just here for convenience, and the declarations are global.
The Jessie plug-in takes advantage of the axioms enclosed in the
axiomatic to infer reads clauses for the declared symbols, so that it
is really important to group together declarations and their defining
axioms. Other than that (in particular if you use WP which relies
solely on user-provided reads clauses), axiomatics are just there to
help you structure syntactically your ACSL environment, and do not
play any semantic role.

Specification modules (section 2.6.11) would provide you namespaces,
but their are not implemented in Frama-C yet.
