Changes for version 0.035

  • Properly handle multi-character modifiers like /ee. We now handle /eie as being the same as /eei. Thanks to Anonymous Monk for finding this. Properly handle \g and \k back references that do not correspond to an actual capture group. They are now reblessed into the unknown token, and counted as errors. Thanks to Anonymous Monk for finding this. Add method error() to PPIx::Regexp::Element. This should return an error message when the element is in error -- normally when it has been blessed into the unknown token or structure. Add method modifier_asserted() to PPIx::Regexp::Element. This walks the parse tree backward to determine if the given modifier is in effect for the element.
