A modern programming language that makes developers happier.

it is a pain to do bitwise operations currently

Could you give an example? In all years, I did not find more than a few places where bitwise operations are needed and in those cases 'or' instead of | is fine

working with flags, working with binary formats

talking to c libraries especially that make heavy use of flags

Binary formats are usually in capsulated and do not require more than shl. For flags it is better to use something like a bitset.

Multiplatform bitset would be nice, but it easy to add it on the library level.

That's right I always forget about those bitsets

Jvm has its own bitset. A bit more advanced if I remember correctly.

I hope you've seen my awesome example of abuse of them: `out &lt;&lt; "hello world &lt;&lt; lineSeparator()`

And it's actually a major reason not to submit them
