I am confused. What am I missing?

) { print "True\n"; } else { print "False\n" };
False

This would mean that both [0..9] and [h..z] would have to match.

True

This would mean that both [0..9] and [a..z] would have to match.

False

"3" is in the string.  Why False?


my Str $x="abc3defg"; if $x.match( / ^ <[a..h]> ** 8 $ / ) { print 
"True\n"; } else { print "False\n" };
False

a and b and c and d and e and f and g are also in the string.
Why the false?
