4.1 and 4.10 are not the same thing, as the period in a software version is not a decimal point. Do you think US Thanksgiving falls on 0.5 this year (since 11/22 is 0.5)? For that matter, how do you explain version 4.1.1? That's not even number!
If you can comprehend dates that use slashes and not divide them out, or subtract ISO style dates (2012-11-22: US Thanksgiving falls on 1979 this year!), then what is the problem with periods as a separator for versions?
IP addresses and ISBN numbers in books must drive you bug nuts. And I imagine you have problems with entering telephone numbers, since your slavish devotion to "all numbers are math" would cause you to multiply the area code by the exchange minus the subscriber code: (202) 456-1414 goes into your contacts as 95258.
Or are you just being as silly as these examples?
