When I see so many programmers mixing integers and fp numbers in
expressions without quite knowing what they are doing (and sometimes
wondering why the heck they don't get the results they are expecting),
I'm thinking: why not different operators. At least, that would force
you to have a clear understanding of both what you want and what is
going to happen, without having to read dozens of pages of the standard
and praying that your compiler sticks to it...


An alternative would be to not do silent type conversion in expressions --
except perhaps (for convenience) for some forms involving constants.

If there is no operator for  int + float  then the programmer would
have to put in explicit type casts as necessary, thus forcing the
programmer to pay attention at each substep to the types.


Such a scheme might do interesting things to expressions such as
  toupper(HexChar) - 'A' + 10
due to the signed-ness ambiguity of char...


Except that there are no char's in that expression, only three int's. ;)
