Also, errors are mostly pretty good and getting better. I think a big and overlooked part of learning a new language is the quality of the errors the language provides. Some do this better than others, and some get it right in the core language but by the time you've stacked up enough libraries and extensions to get things done nicely, the errors aren't so good anymore because they talk about things at a lower level than you're thinking of them (Perl 5 can fall prey to this latter problem, even though the core language has pretty good errors these days).
