Hello,

Would it be possible to consider that:
  1. the regular expressions in the Str library are matched in a greedy
     fashion (longest match, left to right),
  2. that the regexps of an alternative are tried from left to right?

Illustration of case 1 (micmatch/ocamllex syntax):

# match "abc" with RE (_* as s1) (_* as s2) -> (s1, s2);;
- : string * string = ("abc", "")

Illustration of case 2:

# match "ab" with RE "a" | "ab" as s -> s;;
- : string = "a"
