Subject: Proc Question

As I was coding this morning, a question occured to me. Why must proc objects
have a call method? I'm sure that there's a good reason for this, but it seems
like it would be more natural for proc objects to behave as regular methods
do and avoid the .call() syntax.

I.e.,
square = proc {|n| n * n}
square(4) # => 16

I see that [] is aliased to .call, but I find that surprising over (), which
is the more typical way of specifying arguments to a method. Perhaps having
a call method is a more object-oriented way of using proc objects?

Thanks,
Travis
