Comment (by jmantysalo):

 Well, for now we have for example

 {{{
 is_eulerian()   Return True if the graph has a - -
 is_planar()     Test whether the graph is - -
 is_circular_planar()    Test whether the graph is - -
 is_regular()    Return True if this graph is - -
 }}}

 On #18925 and #18941 I have used "return true if" -phrasing. That can of
 course be converted, but it should be uniform in all parts of the
 software. Was there some discussion about this in sage-devel?

 And btw, should every function document the output type? As an example,
 `has_bottom()` in posets is documented as "Return True if the poset has a
 unique minimal element." in the index of functions, and then "Return True
 if the poset has a unique minimal element, and False otherwise." in the
 function itself. There is no explicit `OUTPUT`-part.
