Thanks. I'm currently running 6.12, so this may be what convinces me to go
ahead and upgrade.

How would I change it so that it returns #'(2 2 a 2 2 b 2 c) instead of
#'((2 2 a) (2 2 b) (2 c)) ?
I don't want

Use `~@` (sine Racket 7.0):
(syntax-parse #'(1 2 2 a 2 2 b 2 c)
[(1 (~seq n:nat ...+ x) ...)
#'((~@ n ... x) ...)])

Given this macro that I'm experimenting with:
(syntax-parse #'(1 2 2 a 2 2 b 2 c) [(1 (~seq n:nat ...+ x) ...) #'((n ...
x) ...)])
How would I change it so that it returns #'(2 2 a 2 2 b 2 c) instead of
#'((2 2 a) (2 2 b) (2 c)) ?
I don't want the parens around the individual sequences that
5 matches
