Is there things like intent(in), intent(out) in Julia?

I cannot explain very well why, but I remember kargl said something like, adding intent(in) for x, and intent(out) for y, and realizing that sin is a pure function, it definitely can help the compiler to realized that it should just calculate

I’m surprised about that since the compiler needs to check the correctness of the intent anyway so it doesn’t feel like that should give any more information.

In Julia, there is the convention of adding a ! to the end of a function that mutates an argument and has that argument be the first one, see Style Guide · The Julia Language.
