Are there any Ruby programmers on the list that can
explain to me why this snippet of code:

def foo(a,b="four",c)
  puts("Arg1: #{a}")
  puts("Arg2: #{b}")
  puts("Arg3: #{c}")
end
foo('one','two','three')

produces these errors:

./test1.rb:3: syntax error, unexpected ')', expecting '='
./test1.rb:7: syntax error, unexpected kEND, expecting $end

instead of this result:

Arg1: one
Arg2: two
Arg3: three

Thanks for any input.

You either need to specify a default argument for 'c', or move b to the
end.  You can't have any arguments without defaults occurring after an
argument with a default value.

That certainly explains it.  Thanks a batch.
