Being a Modula-2 like safety language with curly brackets, plenty of @ and .{ } characters already puts it off for me.

For me any alternative to Rust implies having automatic resource managment, eventually coupled with improved type system, in a mix of affine types, linear types, effects or dependent types.

Something that in regards to safety is already available today by using GCC's Modula-2 frontend, FreePascal and similar, is not bringing too much to the table, comptime notwithstanding.
