`match` and `=~` arg order

[dshemetov]

Not a big deal, but the part in the docs that says that =~ is an alias for match confused me, since they actually swap arguments: match pattern target vs target =~ pattern. You can try this out: [("send" =~ "s"), (match "s" "send")] to confirm.

Oh good catch! I didn't really think about order of infix operators implying an order on the non-infix versions, but we should def adjust the docs.
