Several have asked me to go ahead and file an RT report
for the failing test in t/op/calling.t (currently test #91)
so that people aren't left wondering why it fails.
Currently Parrot has a variety of troubles with :slurpy and
:slurpy :named both appearing in parameter lists. In
particular, given a function such as
.sub foo
.param pmc array :slurpy
.param pmc hash :slurpy :named
...
The following call to foo will lose one of the values of $P0:
.sub main
$P0 = new .Hash
$P0['a'] = 11
$P0['b'] = 22
$P0['c'] = 33
foo(0, 1, $P0 :flat :named)
That is, when sub foo is executed, "hash" will appear to have only
two entries in it instead of three. (This is test #91 in t/op/calling.t.)
Surprisingly, it seems to work properly if a named argument is explicitly
given in the argument list:
.sub main
$P0 = new .Hash
$P0['a'] = 11
$P0['b'] = 22
$P0['c'] = 33
foo(0, 1, 'XXX'=>0, $P0 :flat :named)
That is, when sub foo is executed here, "hash" correctly has
four entries in it. This is test #92 in t/op/calling.t (and
for the moment I'm using this approach in PGE as a workaround
for the bug).

Fixed. Thanks for the test.
