Dear perl 6 users,
I am trying to pass a Nil value to a method new of a class that expects a Str. The method new will assign this Nil value to a Str member variable. Then, this value will change during runtime. At the moment I am getting this error: Type check failed in binding $value; expected Str but got Nil Here is an simplified example of what I'm doing: class MyClass { has Str $.value is rw; method new (Str $value) { return self.bless(:$value); } submethod BUILD (Str :$!value) { } } $myObject = MyClass.new(Nil); # << this triggers the error I expect $.value to hold Strings, but I want to be able to instantiate MyClass whether I have a value already or not, and I also want to be able to tell if $.value has a real String or not. Is this possible? If anyone knows a way to do it or has any clue to solve this case, I would be glad to hear about it. Thanks to all in advance, Emiliano
