Hello Alex,

GNU Guile 1.9 now uses your implementation of ‘match’ as a nice
replacement for Wright’s implementation, so thank you!

I stumbled upon this incompatibility: Wright’s ‘match’ supports ‘..1’,
‘..2’, etc., which mean “1 or more”, “2 or more”, etc., and the
associated variable (when there’s one) is bound to the list that

  (match '(a 1 2) (('a x ..1) x))
  => (1 2)

AFAICS these patterns aren’t implemented in your ‘match’.

Do you have plans to implement them?
