Numeric literal very badly optimized
Compile the following program with -ddump-simpl
main = interact $ show . (< 1e40) . readNote how there's no literal value 1e40::Double anywhere in the code. Instead there's a call to fromRat to do the conversion.
Now replace 1e40 with (1e40::Double), and the code looks good. So it seems that when defaulting is involved the code is much worse.
