error: main function not found

error: internal compiler error: src/librustc/hir/map/mod.rs:379: local_def_id: no entry for `22`, which has a map of `Some(EntryExpr(NodeId(20), expr(22: ::std::ops::RangeTo{end: 10,})))`

note: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report: https://github.com/rust-lang/rust/blob/master/CONTRIBUTING.md#bug-reports
