Describe the bug

I created a mutable list which contains strings and paths at initialisation.
I want to append more items in the list using the ++= operator but the script won't compile, nu telling me it cant append list in list.

How to reproduce

Compile this :

mut args = [ 
    hello                        # string type
    ("hello" | path join world)  # path type
]
# => args is list<any>

$args ++= [ foo bar ]            # only strings

Nushell raise an error :

Error: nu::parser::type_mismatch (link)

  × Type mismatch during operation.

    ·                    ╰── expected list<any>, found list<string>

    ╰────

Expected behavior

Being able to append list of any fixed type (e.g. list<string>, list<int>, list<path>, ...) in a list<any>

Configuration

Additional context

In my example above, replacing $args ++= [ foo bar ] by $args = $args ++ [ foo bar ] works well
