[BUG] Cannot pass boolean overloaded object as value to Type::Params named_to_list option

[XSven]

I want to use true and false of the boolean module. I am running into trouble setting the Type::Params named_to_list option to true:

perl -Ilocal/lib/perl5 -Mboolean -MTypes::Standard=Str -MType::Params=signature -e'signature( named => [ name => Str ], named_to_list => true )'
Not an ARRAY reference at local/lib/perl5/Type/Params/Signature.pm line 742.

The problematic line is resumably L55.

Yeah, I suppose I should change it to:

if ( $self->{named_to_list} and not is_ArrayRef $self->{named_to_list} ) {

As a workaround, you could use:

named_to_list => ~~true

... which is kinda readable. Or if your Perl is recent enough:

named_to_list => builtin::true

The coercion attribute seems to have a similar deficit. You cannot say

coercion => true
