I've got this generic function: https://pl.kotl.in/cv6sdbHHy

[hoang]

my question is why does this compile?

[hoang]

oh should I put the code directly here instead of a playground link?

[Joffrey]

T is inferred by the compiler, and in your case inferring Any makes it work, so the compiler chooses this

[Joffrey]

(yes if the code is small it's easier to just put it here)

[Joffrey]

If you want to experiment or clarify those things, you can try specifying the type of T explicitly, as in:

a.isOneOf<String>(1.2, 3)

And this will fail as you expect

oh ok, got it. Thank you.
