Possible silent conversion of u64 to f64

[mike-ward]

mut num := f64(0.0)
num = strconv.atof64(some_string) or { strconv.double_minus_infinity }

strconv.double_minus_infinity is u64. This compiles OK but I feel it should be an error because a u64 is converted to a f64 in the or clause

You're right, this is a bug.
