But for us normal users, this idea can be more than a smooth way to enter data, but also a time saver, skipping the few tries until the correct format is entered.

My other pet hate is fields that simply limit the number of but include spaces in the count. For example phone numbers and credit cards. I should be able to paste or type with spaces between arbitrary character groups (e.g. ‘xxx xx xxxx’) and only the actual characters count towards the limit. I’d expect the whitespace to be removed by the app on blur or submit and only get an error once this has been done.

I’d love to see something like this integrated within common frameworks e.g. AngularJS that I’m playing with at the moment.

I very much like the idea of a domain model attempting to extract the correct information from an input and then deferring validation. It’s a bit of a wonder that we’re so used to the status quo of immediately punishing the user whenever they get something wrong.
