Ada was designed over a period of years (approximately, 1976 - 1983) with experienced compiler designers as key members of the design team. Because of this, certain features such as static binding (the specification of attributes of various data types before execution time) became part of the language design.
Other languages such as SmallTalk (See BYTE, 1981) were designed to aid the problem solving process. C was designed for ease of programming. Efficient implementations of both of these came later.
Designing a language and designing its implementation go hand in hand. Efficient compilers have made (Ada) or broken (PL/1) a language.
