With regard to parser errors, experimentation shows that in ANTLR 3.0.1
1) a global directive of the form
        @rulecatch { catch (RecognitionException e) { } }
    works
2) a local directive of the form
        catch [RecognitionException e] { } directive
    works and has higher precedence than the global directive if present
3) a local directive of the same form as the global directive is accepted
    but does nothing
The last point is weird. Ter?
