Hello, how to deal with default argument "during runtime"?
<https://youtrack.jetbrains.com/issue/KT-64545/Provide-a-way-for-passing-default-argument-explicitly|https://youtrack.jetbrains.com/issue/KT-64545/Provide-a-way-for-passing-default-argument-explicitly>

There isn't really a good way to do this automatically.  You'd be better off putting the default values at a higher level that can be referenced by the calling code.  This would be a clearer pattern anyway.

Sometimes the default value is written by user and the caller is generated by KSP. That's a problem. Currently generate bytecode directly is almost the only way to achieve that.

`Foo().apply { copy(…) }` could be a workaround 

Assuming a data class, that could be one approach. 

I edit the issue on YouTrack, now it's more clearly to describe what I want to achieve. Avoid a X-Y problem.
