V 0.3

30 Jun 2022

• C to V translation via C2V: v translate file.c. (Demo video: Translating DOOM from C to V, building it in under a second and running it!)
• Lots of bug fixes in V, cgen, and C interop to allow running translated DOOM.v.
• Programs built with the V compiler no longer leak memory by default.
• Closures. All operating systems are supported. (Demo)
• Option and Result are now separate types: ?Foo and !Foo respectively. Old code will continue working for 1 year and will result in a warning/hint.
• Hundreds of new checks in the type checker.
• All V's backends have been split up into separate processes. As the result, building V got 26% faster.
• Maps and arrays can now return optionals: m[bad_key] or { ... }, if x := arr[key] { ... }.
• ustring has been replaced with []rune (works just like in Go).
• Maps can now have non-string keys.
• A new compiler pass for transforming the AST (doesn't slow the compiler too much, adds about 25ms to v self). It eliminates unreachable branches and performs other simple optimizations and transformations.
• C backend is now parallel (just the cgen part for now).
• Lots of compiler source code clean up and minor optimizations. The compiler got ~30% faster according to fast.vlang.io.
• Better compiler source code organization (absolutely necessary as it's surpassed 100k loc).
• The naming of V's integer types is now more consistent: byte has been renamed to u8. Old code will continue working for 1 year and will result in a warning/hint.

• Generic interfaces.
• TCC is now bundled with the language, this allows building V programs without an external C compiler dependency.
• Null can be used in unsafe only (for example, for C interop).
• Pointer arithmetics and comparing pointers to numbers is now also only allowed in unsafe.
• Inline sumtypes.
• New module compress.gzip.
• Lots of net/net.http/vweb fixes (also used for the upcoming Gitly launch).
