this also implements multitest support, which fixes #280 Fixes some other preexisting bugs: * MetaLets did not simplify themselves correctly in some nested cases * Library prefixed identifiers did not work as lvalues in opassign * dsetindex/dput/[]= methods did not return a value * checker did not correctly handle invalid constructor field initializers * cascades did not correctly work with method invocations(?) * postfix ++/-- did not correctly generate lvalues in some cases The good news: because this reuses on our existing lvalue/metalet helpers, it managed to flush out a lot of bugs in other features that use them.
