NOTE: Defined in +active_support/core_ext/kernel/reporting.rb+.
h4. +require_library_or_gem+
The convenience method +require_library_or_gem+ tries to load its argument with a regular +require+ first. If it fails loads +rubygems+ and tries again.
If the first attempt is a failure and +rubygems+ can't be loaded the method raises +LoadError+. A +LoadError+ is also raised if +rubygems+ is available but the argument is not loadable as a gem.
For example, that's the way the MySQL adapter loads the MySQL library:
<ruby>
require_library_or_gem('mysql')
</ruby>
NOTE: Defined in +active_support/core_ext/kernel/requires.rb+.
h4. +in?+
The predicate +in?+ tests if an object is included in another object. An +ArgumentError+ exception will be raised if the argument passed does not respond to +include?+.
