The programming language Ada83, has the ``exit'' statement, which is a more
powerful form of ``break,'' since it allows jumps out of nested loops.
Loops can be named, ``exit name;'' continues with the statement following
the named loop.

To quote from section 1.3, ``Design Goals and Sources,'' of the Ada
language standard:

1    Ada was designed with three overriding concerns: program
      reliability and maintenance, programming as a human
      activity, and efficiency.

2    The need for languages that promote reliability and simplify
      maintenance is well established.  Hence emphasis was
      placed on program readability over ease of writing. [...]
      Furthermore,
      error-prone notations have been avoided, and the syntax
      of the language avoids the use of encoded forms in favor of
      more English-like constructs. [...]

3    Concern for the human programmer was also stressed
      during the design.  Above all, an attempt was made
      to keep the language as small as possible, given the
      ambitious nature of the application domain. We have
      attempted to cover this domain with a small number
      of underlying concepts integrated in a consistent and
      systematic way. Nevertheless we have tried to avoid the
      pitfalls of excessive involution, and in the constant search
      for simpler designs we have tried to provide language
      constructs that correspond intuitively to what the users will
      normally expect.

Section 1. Introduction:

1    Ada is a programming language designed in accordance
      with requirements defined by the United States Department
      of Defense: the so-called Steelman requirements. Overall,
      these requirements call for a language with considerable
      expressive power covering a wide application domain.
      As a result, the language includes facilities offered by
      classical languages such as Pascal as well as facilities
      often found only in specialized languages.  Thus the
      language is a modern algorithmic language with the
      usual control structures, and with the ability to define types
      and subprograms.
