map:{
    # your service name, camel case, initial uncapitalised
    ; serviceName = fess

    # package for your domain name, e.g. com.example
    ; domainPackage = org.codelibs.fess

    # keywords for environment properties, same as directory name
    ; environmentList = list:{}

    # environment dispatch by lasta.env of system property?
    ; isUseLastaEnv = false

    # settings for web applications

- AWS S3's [reserved keywords](https://docs.aws.amazon.com/AmazonS3/latest/dev/s3-glacier-select-sql-reference-keyword-list.html) list is not yet respected.

So, we get a Pydantic model from the data in another Pydantic model.

#### Unwrapping a `dict` and extra keywords

And then adding the extra keyword argument `hashed_password=hashed_password`, like in:

```Python
UserInDB(**user_in.dict(), hashed_password=hashed_password)
```

...ends up being like:

```Python
UserInDB(

    override val isInline: Boolean
        get() = withValidityAssertion { psi.hasModifier(KtTokens.INLINE_KEYWORD) || psi.property.hasModifier(KtTokens.INLINE_KEYWORD) }

    override val isOverride: Boolean
        get() = withValidityAssertion { psi.property.hasModifier(KtTokens.OVERRIDE_KEYWORD) }

    override val hasBody: Boolean
        get() = withValidityAssertion { psi.hasBody() }

    override val isInline: Boolean
        get() = withValidityAssertion { propertyPsi.hasModifier(KtTokens.OVERRIDE_KEYWORD) }

    override val isOverride: Boolean
        get() = withValidityAssertion { propertyPsi.hasModifier(KtTokens.OVERRIDE_KEYWORD) }

    override val hasBody: Boolean
        get() = withValidityAssertion { false }

    override val parameter: KtValueParameterSymbol by cached {

        get() = withValidityAssertion { psi.hasModifier(KtTokens.SUSPEND_KEYWORD) }

    override val isOperator: Boolean
        get() = withValidityAssertion { psi.hasModifier(KtTokens.OPERATOR_KEYWORD) }

    override val isExternal: Boolean
        get() = withValidityAssertion { psi.hasModifier(KtTokens.EXTERNAL_KEYWORD) }

    override val isInline: Boolean

    override val isInline: Boolean
        get() = withValidityAssertion { propertyPsi.hasModifier(KtTokens.OVERRIDE_KEYWORD) }

    override val isOverride: Boolean
        get() = withValidityAssertion { propertyPsi.hasModifier(KtTokens.OVERRIDE_KEYWORD) }

    override val hasBody: Boolean
        get() = withValidityAssertion { false }

    override val valueParameters: List<KtValueParameterSymbol>

Pythonにおける「**呼び出し可能**」とは、Pythonが関数のように「呼び出す」ことができるものを指します。

そのため、`something`オブジェクト（関数ではないかもしれませんが）を持っていて、それを次のように「呼び出す」（実行する）ことができるとします:

```Python
something()
```

または

```Python
something(some_argument, some_keyword_argument="foo")
```

これを「呼び出し可能」なものと呼びます。

## 依存関係としてのクラス

Pythonのクラスのインスタンスを作成する際に、同じ構文を使用していることに気づくかもしれません。

例えば:

```Python
class Cat:
    def __init__(self, name: str):

internal val KtDeclaration.ktVisibility: Visibility?
    get() = when {
        hasModifier(KtTokens.PUBLIC_KEYWORD) -> Visibilities.Public
        hasModifier(KtTokens.PROTECTED_KEYWORD) -> Visibilities.Protected
        hasModifier(KtTokens.PRIVATE_KEYWORD) -> Visibilities.Private
        hasModifier(KtTokens.INTERNAL_KEYWORD) -> Visibilities.Internal
        else -> null
    }

internal val KtDeclaration.ktModality: Modality?
