Well, I'll do it in 14,994 lines less as you estimated:

class Inc {
  private int n;
  public Inc(int n) {this.n = n;}
  public int inc(int i) {return n+=i;}
}
public Inc foo(int n) {return new Inc(n);}


Including certain constructs (functions beeing first-level objects, inline
function declaration) in the language specification is not always a good
decision, since it make the language itself more complex. Best example for
this is the huge discussion about multiple inheritance in C++ which some
designers think of a bad idea.

For ruby however, lambda's is a good thing! ;-)


Ciao, Imi
