Cons
Con Not compatible with Windows
How ridiculous is it that a general-purpose language doesn't support the most general PC operating system on the market?
Con Not many third party libraries available yet
Con Rapid changes in a language syntax/features
Since V language under a continuous development and core syntax and features will be "frozen" in a version 1.0.0, updating from older version of a language can cause a code rewrite of previously working program.
Con V 1.0 release was planned for December 2019
The first version of the language was publicly released in June of 2019, version 0.1.x. First beta version of the language was released June of 2022, version 0.3. x. Language has progressed faster than most. Welcomes contributors to join the project.
