+\r
+There should be standard Perl syntax for capturing both streams ;). I\r
+can add a separate parameter instead, but Perl doesn't seem to have\r
+keyword-arguments. At least, nmbug relies on assumptions about\r
+argument values:\r
+\r
+ sub git_pipe {\r
+ my $envref =3D (ref $_[0] eq 'HASH') ? shift : {};\r
+ my $ioref =3D (ref $_[0] eq 'ARRAY') ? shift : undef;\r
+ my $dir =3D ($_[0] eq '-|' or $_[0] eq '|-') ? shift : undef;\r
+ =E2=80=A6\r
+ }\r
+\r
+to map positional arguments back into particular semantic meanings.\r
+That seemed ugly enough (can we only have a single boolean argument\r
+with this pattern?) that I'd prefer piggy-backing on Perl's\r
+stream-direction syntax. But let me know what you like best, and I'll\r
+go that way with v2. I'd be happy to rewrite nmbug in Python too,\r
+which has (to my eyes) much saner kwargs and subprocess handling.\r
+\r
+Cheers,\r
