Accessor

In programming in general, an accessor is a
function designed exclusively to return a variable it represents. While
seeming pointless, accessors are a key part of many programs, including
ENIGMA.

In C++, accessors are most often used to return the values of private
members. This is often done to standardize and unify classes which are
required to offer access to a certain attribute, but are not required to
use a specific implementation. For example, string offers a
length() accessor. In some implementations, this function simply returns
this->size. In the GNU implementation, it returns
((size_t*)data)[-2]. In a really shitty implementation, it may return
strlen(data).

In ENIGMA, accessors are used mostly for cross-scope access routines;
namely, dot access. Accessors are generated and
called automatically by the ENIGMA
compiler in order to get more complicated
games to run.
