What is interesting about it is, DMD already has the solution, and it is
there, implemented!
Just check the page :
http://www.digitalmars.com/d/2.0/float.html
Read the constant folding.
If you already have this capabilities, why limit the user?
It's a bit surprising how D treats numeric literals. Although (say) 2.1
is of type double, 2.1f is of type float, and 2.1L is of type real, they
all have exactly the same value. (Not entirely true. Oddly, the maximum
exponent value does seem to be limited. I think that's something which
should change, as I don't think it makes much sense).
The type only affects the type of expressions involving that value, it
doesn't change the value.
Range propagation isn't fully implemented in DMD2 yet. Once it's in, the
situation will improve a little more. It's already much better than
the situation in C or C++. But I agree that it's still not perfect.
C was a great language but lets get over with this backward-support
paranoia. :)
Thanks.

Hello, after a little discussion on D.learn, i better ask this here
since i didn't get much replies.
Two lil questions.
Why "3" is an int?
Why "0.3" is a double?
Thanks!
