reinterpret_cast?

`tlsVersion < tls_protocol_version_TLSv12`?

Ditto?

Our style is to just use 0 here.

Sounds good.

Strangely enough, we only want to do that with these two particular protocols here.

I think you're right, even though I think we should change our style in this wonderfully statically-typed language with typed literals.  I'll change to 0.

Also of note: we use c-style casts heavily in WebKit's ObjC++ code.  Maybe we should go through and change them all to c++-style casts.

I think our rule (or at least the rule I follow) is to use a C-style cast for Objective-C and CF types (e.g., (__bridge CFSStringRef)@"hello") and C++-style casts otherwise. Or perhaps more generally, use C++ casts for the code that caused you to create the .mm file and C-style casts otherwise.

https://trac.webkit.org/changeset/255527/webkit was a build fix after this.
