0.4.0 breaks DateTime::Parse

[zerodogg]

After 0.4.0 DateTime::Parse crashes with:

$ raku tzbroken
Could not find symbol '&Parse' in 'Timezones::DateTime'
  in sub MAIN at tzbroken line 5
  in block <unit> at tzbroken line 3

Reproduction script:

#!/usr/bin/env raku
use DateTime::Parse;
use DateTime::Timezones;
sub MAIN {
    my $date = DateTime::Parse.new('Sun, 06 Nov 1994 08:49:37 GMT');
    say "Should not crash";
}

Output with 0.3.9

$ raku tzbroken
Should not crash

This almost certainly is a result of the DateTime is DateTime technique recommended by @lizmat. I'm guess it's that DateTime is DateTime { … } clears entries in the DateTime:: symbol table, but Ill need to test things out to see if I can pinpoint the cause. That said, even if that's the cause, I'm not sure of a way to fix it though — hopefully there's a way.

That said, DateTime::Parse is weird though, there doesn't seem to be a reason that it needs to inherit from DateTime.
