This is small enhancement suggestion :-) (Issue 8049).

The "f" suffix turns a number literal without "." into a float,
while "L" requires a "." in the number literal, otherwise you
have defined a literal of type long:


void main() {
       auto x1 = 1f;
       static assert(is(typeof(x1) == float));
       auto x2 = 1L;
       static assert(is(typeof(x2) == long));
       auto x3 = 1.0L;
       static assert(is(typeof(x3) == real));
}

D has "auto" for local inferencing, so this suffix is able to
cause some problems.

So what do you think about introducing a more specific and less
bug-prone suffix like "R" (eventually using "L" to denote
longs only):

void main() {
       auto x = 1R;
       static assert(is(typeof(x) == real));
}

I agree with this proposal, phasing out 'L' for reals seems like 
a good idea, I didn't even know that it was possible until now, 
so I imagine it can't be stepping on many people's toes.
