in reply to What did you have to Unlearn

Not that it was difficult, but I had to force myself NOT to worry about memory management and garbage collection.

Working with complex data structures (heaps, arrays, lists, btrees, hashes) in C required SO MUCH overhead; in Perl: nada.

It was hard at first not worrying about it :)
