All values in $=pod[*]<config> are always Str, even if different types are
specified. :!foo produces foo => "0", which is now true, so this could be
a bit of a problem.

The problem probably lies in Perl6​::Pod​::make_config, right around " # This
is a cheaty and evil hack."

Tests in S26-documentation/09-configuration.t are failing (but skipped)​:

=begin pod
  =for pod :number(42) :zebras :!sheep :feist<1 2 3 4>
=end pod

$r = $=pod[2].contents[0];
is $r.config<number>, 42;
#?rakudo skip 'non-string colonpair pod options'
{
  is $r.config<zebras>, True;
  is $r.config<sheep>, False;
  isa_ok $r.config<sheep>, Bool;
  isa_ok $r.config<feist>, List;
}
