[Newbies] Debug within an error catching block

Greetings.

In one area of code, I need to set a break point and do some debugging. This code is called deeply within a block that is wrapped up so that the end user does not see errors that occur.

In very simplified form, it is like this:

[ self error: 'Throwing an error' ] ifError: [:err :rcvr | Transcript show: 'Trapped error']

When I 'do it', this example will always trap the error instead of breaking into the debugger (which, quit clearly, it is designed to do.)

While I shudder to think of how easily it could be abused, there is no way to break into a debugger anyway, is there (without finding and disabling the outer block that is sent ifError)? Perhaps a hypothetical self untrappableError or self bringUpTheDebuggerPlease?

Cheers, Clinton
