Summary:
Doing a break inside a nested scope that's not a loop,

e.g.
do {
  guard true else { break }
  print("true")
}

gives this compiler error message:

error: 'break' is only allowed inside a loop, if, do, or switch

which makes you think that you can't do what you're doing at all, while you just have to annotate the scope with a label and break that instead,

e.g.
doLabel: do {
  guard true else { break doLabel }
  print("true")
}

Steps to Reproduce:
Just use unlabelled break inside a non-loop scope

Expected Results:
I expected it to compile, or tell me that for breaking there I needed to use a scope label in the compile error

Actual Results:
It doesn't compile and the error is confusing

Regression:
None I think
