I'm not convinced: the syntax you're proposing implies to duplicate
the pagespec (once in the test clause, and once in the map query), which I find
not only inelegant, which I can live with, but also tiring and unpractical:
my else
suggestion
finds its roots in map queries with rather long pagespecs. On the other
hand, if I'm the only one using map in such a way, I can live with this
heavy duplicated syntax without bloating the map plugin with features
no-one but me needs. On the other other hand, the patch is a 3-liner.
I'm not fixed yet, I'll think about it. --[[intrigeri]]
