- add type infos to VM error messages - add 'Name' to UserFunction objects - add 'expectErrorString' to VM tests - replace vm.expectError() with vm.expectErrorString() to make it more explicit - add source map info to VM error messages - optimization in function calls - add file/line/col info to compiler errors - change stdlib module to be loaded from VM (instead of compiler) so they can be properly loaded after the source is compiled into binary - VM can take builtin modules optionally
