An individual Perl programmer can generate bad code so fast that there might be a lot of damage to undo, but the same programmer working in Java will have certain classes of damage that are difficult to have
Someone once said:
Perl is great for great programmers
Java is great for average programmers
Actually, that was me saying that but I was quoting someone
I still would like to take the time to learn Java. And Smalltalk. And some kind of Lisp.
