Oh, this is not documented yet :-(
from t/pmc/dumper.t:
.sub __dump method
.param pmc dumper
.param string name
.local string subindent
.local string indent
.local string name
(subindent, indent) = dumper."newIndent"()
print "{\n"
print subindent
print "this is\n"
print subindent
print "_"
classname name, self
print name
print "::__dump\n"
print indent
print "}"
dumper."deleteIndent"()
.pcc_begin_return
.pcc_end_return
.end

You can create a data structure and dump it, returning another DS is
not possible.

.sub __dump method
.param pmc dumper
.param string name
.local pmc hash
hash = ...
dumper."dumpHash"( name, hash )
.pcc_begin_return
.pcc_end_return
.end
