Commit SHA-1 hash: af1e6684fd

Runtime Environment:
OS Name: Mac OS X
OS Version: 10.13
OS Platform: Darwin
RID: osx.10.11-x64
Base Path: /usr/local/share/dotnet/sdk/1.0.4

Steps to reproduce

Code like this should be fine

   private static double ASDF(in int point1, in int point2)
    {
        return 1;
    }

This code compiles normally.

Actual behavior

Identifier expected; 'in' is a keyword.
