An Unordered and Incomplete List of Things You Should Probably Never Use/Do in Ruby

(thanks to Zach Drayer and Ben Stiglitz for their feedback)

0. Don't use the implicit $_ style parameters where any reasonably sane person might expect a parameter, like #puts.
1. Don't use the string-manipulation methods included in Kernel, like chomp, chop, sub, and gsub. Call them on String instances instead. If you use these methods in combination with $_ style parameters, you are why we can't have nice things.
2. Don't use callcc, because it's inefficient, leaks like a sieve, and isn't included in most implementations.
3. Don't call Array#pack or String#unpack to store data. YAML/Marshal are more powerful and miles saner.
4. Don't use Kernel#test. Come on, this isn't Perl. Compare the fields of File.stat instead.
5. Don't use Kernel#syscall or IO#syscall. You shouldn't even do this in C.
