When I'll have the time I'll check whether it's correct that it doesn't
work or not...

It's not a dynamic array, but an open array, that's an important
difference. You (currently) can't pass a an array constructor ("[...]") to
a dynamic array parameter (that will change once we support such array
constructors like Delphi does). Check the language reference guide for more
