/**
Exclude keys from a shape that matches the given `Condition`.
This is useful when you want to create a new type with a specific set of keys from a shape. For example, you might want to exclude all the primitive properties from a class and form a new shape containing everything but the primitive properties.
@example
```
import type {Primitive, ConditionalExcept} from 'type-fest';
class Awesome {
name: string;
successes: number;
failures: bigint;
run() {}
}
type ExceptPrimitivesFromAwesome = ConditionalExcept<Awesome, Primitive>;
//=> {run: () => void}
```
@example
```
import type {ConditionalExcept} from 'type-fest';
interface Example {
a: string;
b: string | number;
c: () => void;
d: {};
}
type NonStringKeysOnly = ConditionalExcept<Example, string>;
//=> {b: string | number; c: () => void; d: {}}
```

export type ConditionalExcept<Base, Condition> = Except<
Base,
ConditionalKeys<Base, Condition>
>;
