			Get Safe guarantees rather than merely
			Trustworthy, but with worse constant factors.
		</flag>
		<flag name="semigroups">
			You can disable the use of the `semigroups`
			package using `-f-semigroups`. Disabling this is an unsupported
			configuration, but it may be useful for accelerating builds in
			sandboxes for expert users.
		</flag>
		<flag name="statevar">
			You can disable the use of the `StateVar`
			package using `-f-StateVar`. Disabling this is an unsupported
			configuration, but it may be useful for accelerating builds in
			sandboxes for expert users.
		</flag>
		<flag name="tagged">
			You can disable the use of the `tagged` package
			on older versons of GHC using `-f-tagged`. Disabling this is an
			unsupported configuration, but it may be useful for accelerating
			builds in sandboxes for expert users.
