runtime exception in Regex.regex

[dave-doty]

The function regex : String -> Regex creates a Elm Regex from a String. If given an invalidly formatted regex string, for example, "0)", it throws a runtime exception.

Perhaps this is expected behavior, since regex returns a Regex instead of a Result _ Regex? So perhaps this is a feature request to alter the return type to return Err _ if the input has bad syntax, or at least give some way to test whether a String is a valid Javascript regular expression before calling the regex function.

Thanks for the issue! Make sure it satisfies this checklist. My human colleagues will appreciate it!

Here is what to expect next, and if anyone wants to comment, keep these things in mind.

Sorry, I just noticed that this will be fixed in Elm 0.19:
