The relevant function signature is

YRange)(XRange x, YRange y)
if (isInputRange!XRange && isInputRange!YRange &&
!(isArray!XRange && isArray!YRange) &&
isFloatingPoint!(sumType!YRange));
and when you pass an int[] for y, then it determines that int is
not a floating point and you get an error about not matching the
signature, nothing about why you're not matching it.
A good example of where Atila's concepts library would be
helpful...
