I partially agree - a kw is useful especially if its a nontrivial property.
If a(n) is a polynomial, this should be the definition , and other
(supposedly more involved) alternate definitions / properties
mentioned as comment or formula.
For rational g.f. <=> linear recurrence, the kw "LREC" has already
but here also the property (LREC) should usually be the definition.
If there is half a dozen (or even a whole dozen of), other useful
KW's, I would have absolutely no objection but rather support to
implement them !
@JJJ : keywords FINI and FULL already do exist.
