1 [[!tag patch wishlist]]I quite often find myself repeating a boiler-plate
4 and !*.png and !*.jpg...
6 it would be quite nice if I could conveniently bundle them together into a
7 pagespec "alias", and instead write
11 I wrote the following plugin to achieve this:

72 I need to reflect on this a bit more before I send a pull request. In
73 particular I imagine the strict/warnings stuff will make you puke. Also, I'm
74 not sure whether I should name-grab 'alias' since [[todo/alias_directive]] is
75 an existing wishlist item.
77 Here's an example setup chunk:
80 image: "*.png or *.jpg or *.jpeg or *.gif or *.ico"
81 helper: "*.css or *.js"
82 boring: "image() or helper()"
84 The above demonstrates self-referential dynamic pagespec aliases. It doesn't work,
85 however, to add ' or internal()' to `boring`, for some reason.
