Riga 16:

Stepanov riconobbe il pieno potenziale della programmazione generica e persuase i suoi allora colleghi della [[General Electric|General Electric Research and Development]] (tra i quali, principalmente, [[Dave Musser]] e [[Deepak Kapur]]) che la programmazione generica should be pursued as a comprehensive basis for software development. A quei tempi non esisteva un supporto reale alla programmazione generica in nessun linguaggio di programmazione.

Another reason for turning to C++, which Stepanov recognized early on, was that the C/C++ model of computation which allows very flexible access to storage via pointers is crucial to achieving generality without losing efficiency.

Much research and experimentation were needed, not just to develop individual components, but to develop an overall architecture for a component library based on generic programming. First at [[Bell Laboratories|AT&T Bell Laboratories]] and later at [[Hewlett-Packard|Hewlett-Packard Research Labs]], Stepanov experimented with many architectural and algorithm formulations, first in [[C programming language|C]] and later in C++. Musser collaborated in this research and in [[1992]] [[Meng Lee]] joined Stepanov's project at HP and became a major contributor.
