"min" and "max" are infix operators in Perl 6. From Synopsis 3:
: * Minimum and maximum
:
: $min0 min $min1
: $max0 max $max1
I think they're defined as operators because of some of the
other features one can get from it, beyond just the [max] reduction:
$c = $a max $b; # versus $c = ($a, $b).max;
$d max= $e; # versus $d = ($d, $e).max;
@c = @a »max« @b; # larger element of @a and @b
@e = @a »max» 100; # each element is at least 100
