Thank you for opening this - apologies for the delay, but this is on my list to review and test over the weekend

Thanks for letting me know. I was starting to get worried.

@jefferyshivers , I'm trying to merge but the CI is failing with:

Execution failed for task ':protop-core:protopSync'.
> A problem occurred starting process 'command 'protop''

and I'm not able to reproduce the problem locally. Any ideas what may be causing this?

I'm wondering if it's because of:

plugins {
    id "com.google.protobuf" version "0.8.12"
    id "io.protop" version "0.2.0"
}

in protop-core/build.gradle. Isn't that a circular dependency in that the Gradle plugin uses protop itself?
