Zaxo++. That said, when you specify things that should be illegal, like print(T @foo), perl often tries to DWIM in ways more hurestic then definitional -- by defintion, that should be print(T(@foo)), but since there isn't a sub T, it guesses that you might have meant an inderect object, most of the time. Perl's mostly only whitespace sensitive in rare cases, where there are more then one valid way to parse your code.
