S5: array interpolation
An interpolated array:
/ @cmds /
is matched as if it were an alternation of its elements:
/ [ @cmds[0] | @cmds[1] | @cmds[2] | ... ] /
As with a scalar variable, each one is matched as a literal.
Like this? (Assuming single quotes don't interpolate @foo[...])
@a = ('a', 'b', 'c');
'@a[0]' ~~ m:/ @a /; # true
'@a[2]' ~~ m:/ @a /; # true
'@a[9]' ~~ m:/ @a /; # false
If so, that seems pretty wacky...

I think he means as opposed to a subrule. In Perl 5 terms, there's
an implicit \Q\E around each value in the array.
