I'd suggest you expose both kind of APIs as in:

* https://golang.org/pkg/regexp/#Compile
* https://golang.org/pkg/regexp/#MustCompile

Implementing the `Must` flavor is trivial, just call the standard func
and panic() if you get an error. As a side effect you'll get a unique
point where to panic(), and callers will recognize it's likely yo
panic() because the function has "Must" in its name.

If in doubt, implement only the func that returns the error, the other
is just syntaxic sugar IMHO. Example:

https://golang.org/src/regexp/regexp.go?s=10768:10804#L298

panics() have been, in my Golang experience, a pain to deal with. Most
of the time they are just below a "TODO refactor that sh*t" comment, or
they would deserve that comment anyway. Proper error handling takes
time, but it's an investment that pays of.

My 2c.
