Will attach two files to this bug, quasi-arithmetic.hs and QuasiArith.hs.
Running:
{{{
ghc --make quasi-arithmetic.hs -o quasi-arithmetic
}}}
on these files results in:
{{{
ghc: panic! (the 'impossible' happened)
(GHC version 7.4.2 for x86_64-unknown-linux):
mkUsage
main:QuasiArith BinopExpr{d}[(0B, base:System.IO.print{v 0B}),
(32I, ghc-prim:GHC.Types.IO{tc 32I}),
(40, ghc-prim:GHC.Tuple.(){(w) tc 40}),
(rwP, main:QuasiArith.MulOp{d rwP}),
(rwR, main:QuasiArith.AddOp{d rwR}),
(rwU, main:QuasiArith.BinopExpr{d rwU}),
(rwW, main:QuasiArith.IntExpr{d rwW}),
(r2Ha, main:Main.main{v r2Ha})]
}}}
