That is a constant association, quoted in whatever context you pulled
it from either to just emphasize it is constant or because some
enclosing xl code required it.

I haven't given any evaluation rule for associations (other than
associations which are sequences or nil).

`program' doesn't need to be quoted in that example because it is
nested inside of an already quoted association ("  '#( ... )  ").
