I should add that this list is repeated over and over in slight variations throughout the
grammar. Thus, for example, double_literal does include all the inlines including
#subscript, but not #single_literal or #double_literal. This is very hard to read and
maintain, and it is easy to make a mistake. But I know in every case what I want to say in
terms of "all of them, except for these few", so it would be really great to be
able to _say_ that. m.

Here's a list of includes from one of the inline
patterns in the AsciiDoc grammar I'm writing:
{ include = '#double_bold'; },
{ include = '#double_italic'; },
{ include = '#double_literal'; },
{ include = '#double_unquoted'; },
{ include = '#double_quote'; },
{ include = '#single_bold'; },
{ include = '#single_italic'; },
{ include = '#single_literal'; },
{ include = '#single_literal_nopassthru'; },
{ include = '#single_unquoted'; },
{ include = '#superscript'; },
{ include = '#characters'; },
But it happens that that list is almost the same as the #inline group I've already
defined. I could reduce this to a single include! There's just one problem: we must
not include ourselves, i.e. #subscript; we crash if we do, and anyway it's wrong (this
pattern is not in any way recursive). Thus I request that the grammar should allow me to
talk like this:
{ include = '#inline'; },
{ exclude = '#subscript'; },
This is not just to make the list shorter; it also makes the list more correct and
coherent, because I'm allowed to say (and see) exactly the truth: "include
everything except yourself".
Thanks for thinking about this - m.
