=head2 Using another suffix

Do not change the suffix unless you truly must.

If for some reason you cannot use the standard C<_c> suffix, you
can override it by changing C<$AutoCurry::suffix> I<for the duration
of your calls to AutoCurry>.  Use C<do> and C<local> to limit the
scope of your changes:

    use AutoCurry;  # suffix changing is not compatible with ':all'

    my @curried_fns = do {
        local $AutoCurry::suffix = "_curry";
        AutoCurry::curry_package();
    };
    # result: ( "main::foo_curry" )

    sub foo { ... };
    # foo_curry will be created by call to curry_package, above
