This disconnect here, is that Mikkel (OP) wants the Str type constraint for
the file list. Which still works with the @ sigil-
> my Str @more_files; @more_files.push('one.file','two.file');
[one.file two.file]
> @more_files.push(99)
Type check failed in assignment to @more_files; expected Str
The problem with `$files` is the `$`
When a `for` loop sees something that is itemized / containerized
(`$`) it treats it as a singular value.
my @a = 1,2,3;
my $a = @a;
for @a { .say }
# 1
# 2
# 3
for $a { .say }
# [1 2 3]
for @a.item { .say }
# [1 2
You could use the @ sigil for your files variable, too. Then you can
just "for @files". There's two ways to get that to work:
my Str @files = "Test", "Test 2";
or
my @files := Array[Str].new("Test", "Test 2");
Hope to help

Try either 'for @$files' or ' for $files.list'.
