I'll try that.
Oh, I forget I hate breaks anyway, except for the summer one.

Well, let's, as there is no confusion!

I don't know either,
as I don't know your associations,
but you should.
GoTo is not vague at all,
perhaps less vague than breaks,
as breaks presume the programmer to know
the innermostness of the loop concerned.
GoTo can also exit loops, subroutines, functions,
and would bfeak the internal loop/subroutine/function-stack
if not designed to clean up the structure-mess just as a break does.
Both break the integrity of the programming confinement they are in,
and so also destruct the sanity of the structural programmer's mind,
which I think is even more important then internal stack-garbage-disposal.
=====
btw:
Historically [ancient BASIC] GoTo was the only way to do an IF-statement,
before the inline "Then"-keyword was introduced:
If z2 = 5 Then a1 = a1 + 1
had to be written:
110 If z2 <> 5 GoTo 130
120 Let a1 = a1 + 1
130 Remark ComeFrom 110 or 120
In VisualBasic there still is some remnant to be found in:
On Error Goto Next/Resume
