error[E0658]: inclusive range syntax is experimental

Hi, your work looks interesting, but I can not compile the program:

    |                                                        ^^^^^^^^^^^^^^^^^^^^

What rust version do you use? Run rustc -V. I think the inclusive range syntax is enabled in the current stable release.

[Philipp Emanuel Weidmann]

Inclusive range syntax was stabilized in Rust 1.26. As stated in the README, that is the minimum version supported by Hegemon.
