In that case, is there any reason why elsif needs to be a reserved word
outside of that context?
Iâm also trying to plan ahead with regard to adding all keywords to the
CORE:: namespace.
It should be possible in the future for the âifâ keyword to be
implemented as a CV named &CORE::if, which has its own custom parser
that eats the elsif and else keywords.
But it wonât make much sense for there to be a &CORE::elsif subroutine.
It would just be a stub that produces a syntax error when inlined.
Maybe that does make sense. Then we could always change it later.
