readonly array cannot be assigned to the mutable type 'InternalNamePath'

For reusability and readability purpose, I like to have my NamePath stored in constant variable on the top of the file.

To have type support I need the variable's type to be string literal tuple. The simplest way to make an array a string literal tuple is to add as const after it.

However, as const also add readonly to them, making it not assignable to InternalNamePath.

I like the simplicity of as const and I don't think the InternalNamePath is ever actually mutated.

would it be possible to add readonly in front of (string | number)[] to make the InternalNamePath support this?
