code is not valid [current] coffeescript

[bdirito]

build script just calls $ coffee [...]

However OMS is not valid coffeescript. I assume this is due to some coffee language update. The code either needs to be updated to current coffeescript standards and/or include a coffee compiler version specification.

    (return i if o is obj) for o, i in arr

[stdin]:3:6: error: cannot use a pure statement in an expression
    (return i if o is obj) for o, i in arr
     ^^^^^^^^

It appears this library has not been ported to support coffeescript 2.x. It compiles properly with coffeescript 1.12.7. Install with: npm install --global coffeescript@1.12.7
