[ANN] ppx_regexp 0.2.0 and 0.3.0

I found a bug in 0.2.0 and 0.3.0, which is addressed by the 0.3.1 which is now available in opam. The changes are:

  • Fix accidental shadowing of open from another interface-less module using
    ppx_regexp.
  • Support binding of group 0 and the universal pattern.
  • Switch to ppx_tools_versioned. This provides support for 4.02.3 in the
    main branch.
