Hi,
thanks for all your ideas,

I have used the enum before but turned to Map for some reason, don't know why (getting old I think (hopefully)).


But still, should I open a ticket for the Map/subset thing?

Btw the following has the same problem;

> my Hash $h = {a=>1,b=>2}
{a => 1, b => 2}
> $h<a>:exists
True
> subset mh of Str where $h{$_}:exists
(mh)
> my mh $x = 'b'
Type check failed in assignment to $x; expected mh but got Str ("b")
  in block <unit> at <unknown file> line 1

Greetings,
Marcel

I can’t help but think this can all be solved by using enums?

my enum pv ( <d f g h aa bb ff> );
my pv $x = aa;


??

Hi everyone,

I am trying to create a subset but get errors when used. Surely I do something 
wrong here or is it a bug?

In REPL

my Map $p .= new(<d f g h aa bb ff>.kv.reverse);
Map.new((:aa(4),:bb(5),:d(0),:f(1),:ff(6),:g(2),:h(3)))
subset pv of Str where $_ (elem) $p;
(pv)
my pv $x = 'aa';
Type check failed in assignment to $x; expected pv but got Str ("aa")
  in block <unit> at <unknown file> line 3


Greetings,

Marce
