Java has so little syntax—and yet what little syntax it has is C-ish—that it's mutually intelligible to everybody from programmers who only know C, to programmers who only know Haskell. (Maybe not to programmers who only ever learned 6502 assembler, but they have their own humor books published 40 years ago.)
(Is there a term for this in linguistics? A measure of the eigenvector of mutual intelligibility a language has to all other spoken/written languages?)
