    Oberon-2 -> C compiler
    ======================
  
    (release 0.17.2)
  
      220 LEX source files (scanner for lexical analysis) src/*.l
    4,192 YACC source files (parser for syntactic and semantic analysis
          and part of code generation) src/*.y
      809 C header files (misc. definitions and interfaces) src/*.h
    9,197 C implementation code files (main driver,
          command line handling, symbol table, other auxiliary data types
          and runtime system/library implementation) src/*.c
      707 build, install, and test scripts (sh)
    ------
    15,125 < 16K LOC
    ======
  
    (+6,299 lines of Oberon-2 test code)
  

  Such a very compact code base! Oberon-2 may never have reached the distribution that Pascal had (which was an issue of timing as well due to influential distributions like P-System Pascal and Borland Turbo-Pascal/Delphi), but it's a great exercise in minimalism.

  Is Oberon used anywhere, if so, where? Is it picked for new projects?
