This brings back the good old days of FORTRAN IV which had a 
single-statement IF and no ELSE. Thus:
       C = VALUE1
       IF ( A .EQ. B) C = VALUE2
Notice the indentation. Cols 1-5 were reserved for line # and col 6 for the 
continuation code. So Python is not the only indentation dependent 
language. Nor is it the first to use indentation to convey structure.
