I stumbled across another issue. In the GSM 04.08 specs Information
Elements (attributes) have a minimum and maximum length. I have used
something like the below to handle that.

Object subclass: Foo [
    Foo class >> valueSize: min max: max [

    <valueSize: 1 max: 3>

this can not be expressed with the current classPragmas. So if I would
return #valueSize from the classPragmas then the 'max' would be lost
and if I return #valueSize:max: then it can not perform this selector?

Any idea how to resolve that?

I will add this as another linter (but I think the STInST ast doesn't
have enough information for the pragmas to detect it).
