Your proposals looks nice to me ;-)

Sometimes i want to collect matches for different purposes; feed them into
another functions accepting a list. That's why i miss a standard operator
collecting matches. Sure, it can be done with a `while' loop, and 3-5
lines. With the operator would be just one function call.

You know, the beauty is in the eyes watching. The elegance too. Maybe
you don't like the blue jersey i am wearing now; my mum made it
for me and i love it ;-)
Suppose depend on the name of the operator. Not
a sorprise if `collect-matches' collect matches; a bit of sorprise if
`domatches' does such thing.
Thank you for your opinion :-)
