No tests for reader errors for very large and very small floating point numbers?
Perhaps, I missed it, but I didn't find any tests for reader errors for very small or very large floating-point numbers. See https://www.lispworks.com/documentation/lw60/CLHS/Body/02_caa.htm which says too small or too large exponents for a float should cause a reader-error to be signaled. But too many digits wont cause a reader-error even though those extra digits can't be represented.
