You have it to thank for most current programming languages being easier to parse than, say, FORTRAN or COBOL, whose design wasn't influenced by formal language theory and whose syntax is perverse and irregular.
How quickly we forget John Backus's important and independent work in formal languages ;)
Yeah, but...to quote a biography of Backus,
After FORTRAN, Backus turned his focus to other elements of computer programming. In 1959, he developed a notation called the Backus-Naur Form.What a difference it would have made had it been the other way around! (DO 100 I = 1.10, anyone?)
