int(n) and (int)n have exactly the same effect. But the C++-style int() syntax can only be used with types which have 'simple names' (I think this means eg int but not int *).
This explains btw why the mistaken use of
p = new int(n);
instead of
p = new int[n];
doesn't cause a warning or error: the compiler thinks you want a pointer to a new int, which int has been initialised with n.

Quick
- ($a, $b....) = unpack("A2A7...", $packed)
- push( array, list )
