Question (more or less) about arrays

[Viktoras Didziulis]

in Perl it would return a scalar context of variable in this case it is size
of an array (e.g. number of elements) e.g. $var_size = @var 
thence one can write 
for ($i = 0; $i < @var; $i++) 
{ 
#prints all elements of array @var to STDOUT 
print $var($i); 
}

But here's the tough question: if "var" contains an array, then no 
valid data can be returned by accessing it without the name of one of 
its keys. So what should "var" return when checked directly?
