Template Haskell: Floating point literals that cannot be represented by rationals
Currently, TH expressions and patterns store Float/Double values as rationals: http://hackage.haskell.org/package/template-haskell-2.11.1.0/docs/Language-Haskell-TH-Syntax.html#t:Lit
Unfortunately, this isn't sufficient, as there is no way to properly support usual floating point values such as NaN, Infinity, and Negative-Zero. This is true for both expressions and patterns.
It would be nice if Double/Float literals were stored as double-floats themselves, instead of rationals.
