It sounds like your actions are capture arguments, rather than
separate midpoints (since they're working on the same resource,
anyway).
If you have someoperation as a CaptureArg, and stick that away in the
stash to perform the action later in the chain, you should get what
you want.
I see what you mean, but that means I have to do a reasonable amount
of error handling myself, as there are only a few sets of actions
which are valid..
Also, the number of arguments to access a resource can vary..
My URLs are of the form:
/thing/<canonical_identifier>/further/*/chained/*/things
/thing/other_identifier_p1/*/other_identifier_p2/*/further/*/chained/
*/things
Looking up by the canonical identifier, and another identifier are
also actually different operations, so it'd be nice to be able to
split them, but more to the point what you suggested just won't work,
as I can't just say CaptureArgs(4) - as there can be different
numbers of arguments for various points to join..
If I was to hack some code (and tests) up which supported my
originally suggested syntax ( Chained('sub1', 'sub2') for joining
chains), what would anyone feel about it?
Cheers
Tom
