* Dafny: parallel statements:Gravatar Rustan Leino2012-01-17
| | | | | | | - removed the awkward restriction that method postconditions cannot use old/fresh if there's no modifies clause and no out-parameters; instead, implemented parallel statements to handle these cases - also allow old/fresh in ensures clauses of parallel statements - allow TypeRhs and choose expressions in Call/Proof parallel statements - disallow calls to non-ghost methods in parallel statements (since those may do "print" statements and we don't want to allow those to take place in parallel; besides, the compiler wants to omit the parallel statement altogether and could not do so if there were print statements)
* Dafny: Recheck specifications that contain refined (extended) predicates, ↵Gravatar Rustan Leino2012-01-16

* Dafny: handle refinement of nested tokens that come from SpliExpr (still ↵Gravatar Rustan Leino2012-01-12

* Dafny: make full predicate definitions available only inside a module ↵Gravatar Rustan Leino2012-01-11

* Dafny: allow class-member declarations at top level of any module (not just ↵Gravatar Rustan Leino2012-01-10
