The change of Boolean in r48965 changes multidispatch w/o a deprecation notice:

{{{
pmichaud@orange:/zip/parrot$ cat bool-1.pir
.sub 'main' :main
$P0 = new ['Boolean']
'foo'($P0)
.end

.sub 'foo' :multi(Integer)
say 'foo(Integer)'
.end

.sub 'foo' :multi(_)
say 'foo(_)'
.end

pmichaud@orange:/zip/parrot$ RELEASE_2_6_0/parrot bool-1.pir
foo(Integer)
pmichaud@orange:/zip/parrot$ trunk/parrot bool-1.pir
foo(_)
pmichaud@orange:/zip/parrot$ trunk/parrot_config revision
48981
pmichaud@orange:/zip/parrot$
}}}

This causes at least one Rakudo spectest to fail where it previously succeeded (S03-operators/short-circuit.t test 20).
