PROPOSAL: Implicit conversions of integer literals to floating point

In version 0.80 floating point->integer was disallowed. The reasons that 
triggered that disallowance in 0.80 are symmetric.

A reason was:
   `(4,2)' might be mistyped as `(4.2)'
and symmetric means:
   `(4.2)' might be mistyped as `(4,2)'

Such typing errors are close to undetactability and known to have caused 
tremendous hazard. In D they can be accompanied by the usage of appropriate 
overloads or variadic templates.

Therefore disallowing implicit conversions integer->floating point is the 
right way to go.

Otherwise I will feel no sorry for those who get an output of "21.414" when 
they expected "2.049".
