When Things Don't Match The With Statements
You set up a series of match statements in a with
construct as a way of avoiding a bunch of nested if statements. Inevitably you will be passing data through that doesn't meet all of the match criteria. By default, the with
construct will short circuit and your program will continue from there.
You can, however, take more control over how you handle the failure cases by employing an else
block. The else
block works a lot like a case statement.
Here we are able to anticipate a failure case and respond accordingly. For everything else, we have a generic action that we take.
See the docs for with
for more details.
