Loooong question with much editorializing shall ensue:

A was invented by B at MIT in 1958. One interesting, almost core, feature of A, is its intensely recursive nature. This recursion was to such an extreme that a complete interpreter for A was written in A in “about a page” of code!

Fast forward to 1972. The setting is, of course, Xerox PARC. C and ‘Dan’ were in discussion about powerful programming languages. C, inspired by the one-page nature of A, claimed that he could define the “most powerful language in the world” in a page of code. ‘Dan’ bet him on it, and C eventually did come up with the language D.

Laaate post is continued in the next one.

Identify A, B and C for 1 point.
