Need to evaluate whether any C# 6 features will require changes to the Razor parser

[Eilon]

Please don't close this bug until the C#6 features are finalized (which won't be any time soon). We can use this bug to track potential changes we might need to make to Razor. E.g. imagine a new C# 6 feature has some additional @ signs in it somewhere - we'll likely have to adapt to that.

@NTaylorMullen let us verify out var in a functions block, and ?. @Foo.FirstOrDefault()?.Something

[NTaylorMullen]

?. breaks rendering.

[dougbu]

please be more specific about the exact way you're using ?. and what gets broken. also does the breakage vary depending on

• what's on either side of the ?. e.g. (foo as Bar)?.Beez versus foo?.bar ?
• whether you use ?. or ?[ e.g. foo?.bar versus foo?[bar] or foo?[42] ?

@DateTime?.Now Generates:

Write(DateTime);
WriteLiteral("?.Now");

When it should generate:

Write(DateTime?.Now);
