Thanks! Looks good!
I think two additional test cases would be beneficial. Otherwise, this is an awesome 1st contribution.

[schalkms]

Why did you change this?

[realdadfish]

It served no purpose for the particular test, but rather confused because of the additional @Suppress("ForbiddenVoid").

[schalkms]

I would prefer to have the following test cases:

1. nested generic void usage (e.g. A<B<Void>>)
2. Dictionary (e.g. Map<Int, Void>)

[realdadfish]

Will add these.

[schalkms]

Thanks!
