'needs' is too specific; we need a more flexible test #6

What we have now is effectively "needs all". What about "needs only one" or "needs any"?

Possibly take a sub reference and let people use Syntax::Keyword::Junction:

use Syntax::Keyword::Junction qw/any one/;

my $spec = [
    Param("foo")->needs( sub { $_ eq any(qw/bar baz/) } ),
    Param("baz")->needs( sub { $_ eq one(qw/quux wibble/) } ),

Or, possibly we just make those individual methods (and use junctions internally):

my $spec = [
    Param("foo")->needs_any(qw/bar baz/),
    Param("baz")->needs_one(qw/quux wibble/),

How about adding "excludes" (or something similar) as well?


means that if foo is specified, bar may not also be specified.
