Maybe you mean the context of the assignment?
@array = ( "one", "two", "three" );
($len) = @array;
$len1 = @array;
print "1 - ", $len, "\n";
print "2 - ", $len1, "\n";
Where the first will print "one" and the second will print "3", since (IIRC) assignment forces the context of the LHS onto the RHS.
Update: See ikegami's post below for the correct explanation of what I was trying to say.
