It looks like array dereferencers don't interpolate currently in
double quotish strings, so you were trying to look up '@a[0]' in the
hash. This is likely a bug a Rakudo. I think S02 says that "@a[0]"
should be interpolated and that "@a[]" should be interpolate the way
"@a" does in Perl 5). You can currently say
say %foo<< {...@a[0]} $c >>.join('/');
or
say %f...@a[0], $c}.join('/')
