By using all the previous alternatives I had the chance to learn from all of them, take ideas, and combine them in the best way I could find for myself and the teams of developers I have worked with.

For example, it was clear that ideally it should be based on standard Python type hints.

Also, the best approach was to use already existing standards.

package okhttp3

import okio.IOException
import okio.Timeout

/**
 * A call is a request that has been prepared for execution. A call can be canceled. As this object
 * represents a single request/response pair (stream), it cannot be executed twice.
 */
interface Call : Cloneable {
  /** Returns the original request that initiated this call. */
  fun request(): Request

  /**

      assertThat(it.protocol).isEqualTo(Protocol.HTTP_2)
      assertThat(it.handshake!!.tlsVersion).isEqualTo(TlsVersion.TLS_1_3)
    }
  }

  @Test
  @Disabled
  fun testGoogle() {
    assumeNetwork()

    val request = Request.Builder().url("https://google.com/robots.txt").build()

    client.newCall(request).execute().use {
      assertThat(it.protocol).isEqualTo(Protocol.HTTP_2)

            /* choose (for byte array)
             * public fun byteArrayOf(vararg elements: kotlin.Byte): kotlin.ByteArray
             */
            (it as? FirFunctionSymbol<*>)?.fir?.valueParameters?.singleOrNull()?.isVararg == true
        } as? FirNamedFunctionSymbol ?: return null
        return firSymbolBuilder.functionLikeBuilder.buildFunctionSymbol(firSymbol)
    }

        }
      }

      // There's another part. Parse its headers and return it.
      val headers = HeadersReader(source).readHeaders()
      val partSource = PartSource()
      currentPart = partSource
      return Part(headers, partSource.buffer())
    }

    /** A single part in the stream. It is an error to read this after calling [nextPart]. */
    private inner class PartSource : Source {

    'email': '******@****.***',
    'full_name': None,
}
```

#### Unwrapping a `dict`

If we take a `dict` like `user_dict` and pass it to a function (or class) with `**user_dict`, Python will "unwrap" it. It will pass the keys and values of the `user_dict` directly as key-value arguments.

So, continuing with the `user_dict` from above, writing:

```Python
UserInDB(**user_dict)
```

would result in something equivalent to:

        getTopLevelDeclarations(nameFilter) { it.getTopLevelCallables() }
    }

    override fun getCallableSymbols(names: Collection<Name>): Sequence<KtCallableSymbol> = withValidityAssertion {
        if (names.isEmpty()) return emptySequence()
        val namesSet = names.toSet()
        return getCallableSymbols { it in namesSet }
    }

        return element.getDiagnostics(firResolveSession, filter.asLLFilter()).map { it.asKtDiagnostic() }
    }

    override fun collectDiagnosticsForFile(ktFile: KtFile, filter: KtDiagnosticCheckerFilter): Collection<KtDiagnosticWithPsi<*>> =
        ktFile.collectDiagnosticsForFile(firResolveSession, filter.asLLFilter()).map { it.asKtDiagnostic() }


    private fun KtDiagnosticCheckerFilter.asLLFilter() = when (this) {

    override fun getGetterDeprecation(symbol: KtPropertySymbol): DeprecationInfo? {
        return getAccessorDeprecation(symbol, symbol.getter) { it.getter }
    }

    override fun getSetterDeprecation(symbol: KtPropertySymbol): DeprecationInfo? {
        return getAccessorDeprecation(symbol, symbol.setter) { it.setter }
    }

    override fun getJavaGetterName(symbol: KtPropertySymbol): Name {

```
