(This was originally in dotnet#837.) The grammar has been extended to be as prescriptive as reasonably possible as befits a language specification[1], this means that former statements such as it being illegal to have a set accessor for a ref-valued property are now covered by the grammar. However the usual verbose description of the grammar remains! The term ref-valued rather than ref-returning is used, a term closer to the language of fields. To distingush the two kinds of properties, which do follow different rules, the corresponding and somewhat ugly term non-ref-valued is used (non-ref-returning would be just as ugly). [1] The grammar used by a compiler may be less restrictive to support more descriptive error messages, that is of course an implementation issue! Fixes dotnet#825.

@BillWagner: If you could approve and merge this, that'd be great. It's basically a rebased and squashed version of #837 (which has already been reviewed). |

I just finished looking as well. Thanks @jskeet |
