Syntactic sugar for multiple in tests on a list

[Prathik Rajendran M]

Hi,

Is there any better way to write the following expression

"value-a" in list && "value-b" in list

Perhaps something like the following (but I know that doesn't work)

 ["value-a", "value-b"] in list

I can always write a custom global function, but wanted to know if there is something like this already.

Thanks!

You can use the all macro.

["value-a", "value-b"].all(e, e in list)
