it's unusual to use `self` here.

How about '&' as allowed prefix/suffix for method name as a marker of
mutating method? I.e.
self.&halve()
&halve()
or
self.halve&()
halve&()
Actually, IMO &halve() is not a variant as it probably could be used in
function like
something( &halve ) - confused
so, the suggestion is to have '&' suffix as marker of mutating methid:
self.halve&()
halve&()
