change the modifiers to private from public and lift return out of 'if'

[heli-os]

Hi i am Heli who using ksp.

First, changed some codes to not use the platform type. platform type requires unnecessary boilerplate(!!, let trick, ...) And open source is a guide to writing code.

so i think bad code examples should be deleted.

Second, Lift return out of 'if'

Third, change the modifiers to private from public

thanks. 🙇

I think the change for combining return statement and private val make sense to me, but I don't get the benefit of adding explicit types to the rest of your change, if no specific reasons, maybe let's not touch them.

@neetopia
okay, It would be better not to touch it.

I removed the added explicit type.
