Statement macros are now treated somewhat like item macros, in that a statement macro can now expand into a series of statements, rather than just a single statement. This allows statement macros to be nested inside other kinds of macros and expand properly, where previously the expansion would only work when no nesting was present. See: - `src/test/run-pass/macro-stmt_macro_in_expr_macro.rs` - `src/test/run-pass/macro-nested_stmt_macro.rs` This changes the interface of the MacResult trait. make_stmt has become make_stmts and now returns a vector, rather than a single item. Plugin writers who were implementing MacResult will have breakage, as well as anyone using MacEager::stmt. See: - `src/libsyntax/ext/base.rs` This also causes a minor difference in behavior to the diagnostics produced by certain malformed macros. See: - `src/test/compile-fail/macro-incomplete-parse.rs` |
