This ticket is about failing tests (fudged 'todo') in S06-other/main-usage.t which are about using command line switches without '=':
$ perl6 -e 'sub MAIN(:$xin) { say $xin }' --xin "foo bar" Usage: -e '...' [--xin=<Any>] According to S06 this should be valid and should be equivalent to $ perl6 -e 'sub MAIN(:$xin) { say $xin }' --xin="foo bar" foo bar A leading comment in the test file expresses some doubt about this syntax and mentions this discussion: http://irclog.perlgeek.de/perl6/2011-10-17#i_4578353
