@TODO 10/11/17 Ben Culkin :GrammarReorg
	Better organize the provided sample grammars.

@TODO 10/11/17 Ben Culkin :Determinism
	Add a way to get the grammar to pick rules in a deterministic fashion,
	so as to be able to iterate all of the rules.

@TODO 10/11/17 Ben Culkin :ExportSanity
	Figure out a way to organize exports instead of just sticking them all
	into the global namespace. Maybe use the @ symbol for 'foreign rule
	references' (FRRs)

	ADDENDA: 10/26/17
	We now have the '^<rule>' syntax to avoid shadowing issues, but this
	doesn't avoid the issue with duplicate exports.

@TODO 10/23/17 Ben Culkin :Casing
	Provide some way to convert rules into different cases.

@TODO 10/23/17 Ben Culkin :Spacing
	Find a saner way to do spacing. + rules work well for some things, but
	what is needed is some way to do it only one level deep. Possibly some
	kind of pragma to convert a rule to a single-level spacer?

	ADDENDA: 10/24/17
	We now have a partial solution in 'despace-rule'. Now, grammars need to
	be adapted to use it.

@TODO 10/23/17 Ben Culkin :Pluralizing
	Add some way to say to pluralize the contents of a rule

@TODO 10/23/17 Ben Culkin :Extensions
	Add some soft of pragmas to allow the loading of extensions that provide
	custom rules/case types/pragmas and things like that

@TODO 10/30/17 Ben Culkin :RegexPragma
	Add a pragma that applies a regex substitution to the generated version
	of a rule.

@TODO 4/25/18 Ben Culkin :Debugging
	Add a way to print out the rules as a tree format, so as to perform
	better debugging of rules.

	Once this has been done, consider doing a CLI interface that allows
	manipulating and using grammars.

@TODO 5/10/18 Ben Culkin :Despace
	Add a generalized form of despace-rule that allows inserting arbitray
	text between rule bits. Maybe call it 'intersperse-rule'?

@TODO 5/10/18 Ben Culkin :RuleInclusion
	Add some way to sort of 'import' a rules body into another rule so as to
	not throw off probability by splitting.

@TODO 5/18/18 Ben Culkin :PragmaErrors
	Give better error messages for malformed pragmas
