Saying that exact and inexact numbers can't be a single type is like saying positive and negative numbers can't be the same type. Saying that fractions and floats can't be a single type is like saying ASCII strings and UCS-4 strings can't be the same type within the FSR. "Single abstract Number type" doesn't preclude a "FNR" where some Number objects are represented as floats and others are not. -- https://mail.python.org/mailman/listinfo/python-list
