@doc{*
    This is a literal number annotation, an identifier follows a literal
    number. The syntax for this annotation is
         n_base_N  or n_BASE_N  or n_Base_N
    in which 'n' is a literal number in base 2 to 36 and N is the literal
    number that is the base, in base 10. 'n' can have numbers, underscores, and letters
    but, if it has letters, it should start with a number (otherwise the
    compiler will consider it as an identifier). Both '_' in n_base_N are
    optional. Of course, something like
        0Abase_20
    is illegal because the compiler would consider that the metaobject name
    is 'Abase'. The metaobject uses method 
        Integer.valueOf(n, N)
    to parse the number 'n' in base N.
