I’m reimplementing `SimpleFunctionBuildingContext` because I’d like an alternative API. The `build` instance method calls `buildNamedFunction` and passes a lambda which contains the following statement
```initTypeParameterBounds(typeParameters, typeParameters)```
What’s going on here? As far as I can tell, this is equivalent to
```context.initTypeParameterBounds(
    functionBuilder.typeParameters, 
    functionBuilder.typeParameters,
)```
Where `context: SimpleFunctionBuildingContext` and `functionBuilder: FirNamedFunctionBuilder`.

Check the sources of initTypeParameterBounds:

<@UKPEELJCW> But why does the function hold two references to the same object?

There are two parameters in this function to properly handle the case of inner classes, which see type parameters of the outer class but don't hold them. 

For functions all and own parameters are always the same.

I’ve just noticed that I pinged you again by mistake. I apologise, I’ll be more careful and thank you for the explanation!
