Type MutableList gets converted to List

[mc-lovin]

When I trying to use MutableList class, it sometimes gets converted to just List

example

    val funSpec = FunSpec.constructorBuilder()
        .addParameter("list", MutableList::class.parameterizedBy(Int::class))
        .build()

gets converted to

constructor(list: kotlin.collections.List<kotlin.Int>)

while it should be

constructor(list: MutableList<kotlin.Int>)

There's no such type as MutableList at runtime so the library only sees the runtime type. If you need MutableList then you'll need to use a ClassName to create it.
