ALGOL 68 might-have-beens
S. G. van der Meulen · 1977
This paper discusses some language features which might have been in ALGOL68. They would not have complicated the compiler to any considerable extent. They would certainly have contributed to the expressive power of the language. In fact their desirability emerged from the practice of ALGOL68 programming (cf. {4}). “Might-have-beens” are small super-language features and some of them could even be considered as “might-be”s in the sense that they still might be incorporated in existing compilers without (great) difficulty.
