Separator character in class names

Hi,
I'm relying on decomposing composite class names.
An example class name is  BB5aBank
I decompose it into #(BB5a Bank) but am using ugly and error-prone hacks to achieve it.
It would be very helpful if I could use some kind of separator in the class name, e.g., BB5a:Bank

I've tried brute force by renaming class BB5aBank to BB5a:Bank
This is permitted and Smalltalk points to the renamed class.
Compiling a method that is using the new class name fails:
    bank :=  Expression expected ->BB5a:Bank new
   

I've looked into the Parser code, but got lost.

You probably need to dive down into the Scanner.  For example if you used period and modified Scanner>>xLetter to not terminate the scan if it sees a period followed by a capital letter you'll likely be able to parse e.g. BB5a.Bank as a single token.  If you look at the xLetter method you'll see it already tests self allowUnderscoreSelectors to accept underscores.

Ah, so an alternative would be to make sure the allowUnderscoreSelecctors preference is set and use underscore as your separator.

HTH

Anybody have any ideas?
