This removes the security features added by $SAFE = 1, and warns for access or modification of $SAFE from Ruby-level, as well as warning when calling all public C functions related to $SAFE. This modifies some internal functions that took a safe level argument to no longer take the argument. rb_require_safe now warns, rb_require_string has been added as a version that takes a VALUE and does not warn. One public C function that still takes a safe level argument and that this doesn't warn for is rb_eval_cmd. We may want to consider adding an alternative method that does not take a safe level argument, and warn for rb_eval_cmd. |

There are numerous possible way of categorizing the entities and concepts that
make up a programming language. Ruby has a fairly large number of reserved
words. These words significantly describe major elements of the language,
including flow control constructs like 'for' and 'while', conditional
execution like 'if' and 'unless', exceptional execution control like 'rescue',
etc. There are also literals for the basic "types" like String, Regexp, Array
and Fixnum.
Behavioral specifications describe the behavior of concrete entities. Rather
than using concepts of computation to organize these spec files, we use
entities of the Ruby language. Consider looking at any syntactic element of a
Ruby program. With (almost) no ambiguity, one can identify it as a literal,
reserved word, variable, etc. There is a spec file that corresponds to each
literal construct and most reserved words, with the exceptions noted below.
There are also several files that are more difficult to classify: all
predefined variables, constants, and objects (predefined_spec.rb), the
precedence of all operators (precedence_spec.rb), the behavior of assignment
to variables (variables_spec.rb), the behavior of subprocess execution
(execution_spec.rb), the behavior of the raise method as it impacts the
execution of a Ruby program (raise_spec.rb), and the block entities like
'begin', 'do', ' { ... }' (block_spec.rb).
Several reserved words and other entities are combined with the primary
reserved word or entity to which they are related:
