Pattern matching failture with simple slurps

[fcard]

julia> @letds [*{x}, a, *{y}, 10] = :[1,2,3,4,5,6,7,8,9,10] (x,y)
ERROR: ArgumentError: pattern`([(:*){x}, a, (:*){y}, 10],)` cannot be matched with ([1, 2, 3, 4, 5, 6, 7, 8, 9, 10],)

What the! I was sure those sort of simple things were working before. How am I to brag about having a Regex for Exprs when I can't even do this! Hmm, Regex for Exprs, maybe I should branch that off in its own package, that could interest people more. (it won't) MetaRegex.jl, that surely will catch some eyes. (pffffff)

Also, slurp, what a word to keep saying over and over. Once more I blame it all on Mike Innes, he introduced me to the term! Curse you Mike Innes for making me uncomfortable discussing my package with myself! (moreso!)

Related to GenericGreedySlurp followed by another slurp, hmhm. It's probably not wanting to backtrack when it should.

...
God that code is a mess, I will have to resolve THAT before fixing this. I am getting into issue dependency hell here...

Do you have an estimate for solving the problem? Because I had a very similar package doing regex on expr with trees and state machines, now i am planning to abandon it and use yours.

I have a solution in mind and a good chunk of the code done. I don't have an exact estimate but there shouldn't be too much work left, I just need to find the time to finish it.
