Here are my issues if we try to modify =* and not add another operator: 1) We'll completely abandon having an operator that matches the remaining parts of a version number for good: =cat/foo-5.2015* would no longer work. 2) We'll have to decide if we should remove the leading zeros of a version number: should 5.01.0 and and 5.1.2 be the matched the same if I used =5.01*? We can only either allow it or not. We keep one feature, we lose the other feature. If we use another operator, =5.01* could just stay strict on matching 5.01*, whereas the operator could have the function of treating them like decimals instead. We can keep =* have the string matching feature while have another operator do the more-on-arithmetic one.
