Stef,
For rangeError the code would look like this:
[
(NumericError new)
reason: #rangeError;
signal: 'access out of bounds'
]
on: NumericError
do: [:ex |
ex reasonCode == #rangeError
ifTrue: [ "do your thang" ]
ifFalse: [ ex pass ]].

so it means that I write what?
[] on: NumericError do: [:ex | ]
how do I access the rangeError?
Using Sven's hierachy as a starting point and taking some cues from the
GemStone exception hierarchy, I would suggest the following (names atarting
with # are reasonCodes in the namespace of the parent exception class, instead
of a unique class):
Exception (messageText reasonCode)
Abort
Error
NumericError
#floatingPointException
#rangeError
#naNError
ZeroDivide (dividend)
FileStreamException (fileName)
#fileDoesNotExistException
#fileExistsException (fileClass)
#cannotDeleteFileException
#fileWriteError
#fileReadError **
#fileClosedException **
#cannotAccessFileException **
#readonlyFileException **
MessageNotUnderstood (message, receiver)
#nonBooleanReceiver (object)
OutOfMemory< handlers?>
ControlInterrupt
Halt
AssertionFailure
BreakPoint
CompileError
SyntaxError ** !exists! (input, position)
#numberFormatException **
#headlessError **
TimedOut ** (object, operation, timeout)

#sizeMismatch (objects)
