`JsonObjectBuilder.to` method shadows `to` function from stdlib

[anti-social]

Recently I encountered such a problem. Imagine we have a function like follow:

fun prepareRequest(alias: String): JsonObject {
    return json {
        "alias" to alias
    }
}

Then I did small refactoring:

fun prepareRequest(alias: Alias): JsonObject {
    return json {
        "alias" to alias
        // Fix:
        // "alias" to alias.name
    }
}

And suddenly method to became https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/to.html which result is just lost. The compiler is silent.

Possibly it is worth to rename JsonObjectBuilder.to extension method or make json object construction more explicit.

Seems 'classic' DSL (with to and unaryPlus) for json was a mistake, after all.
