Yes, though we didn't have reduce operators back then, nor did we have infix min and max that would allow you to say

for @list { $min min= $_; $max max= $_; }
But [minmax] @list might be what the OP really wants.

And to answer tye's question, min and max are multiply dispatched, so it depends on the types of each pair of arguments. Non-comparable values probably produce an error, but any ordered type will work if used consistently.

(And my grandparent response was probably bogus, since junctions are really only for doing boolean logic, not pulling out actual values. But given that I was very sick four years ago, I'm not surprised...)
