So anybody can decrypt that?! i´m absolutely stucked by understanding this :D

As Tutorials: Basic debugging checklist teaches, use B::Deparse to see how perl interprets the code

You can also use ppi_dumper or Re: ppiwx / wxPPI / wxppixregexp xPPIx_Regexp_linecol_onize / PPIx::Regexp::Element::column_number to walk the code (or the deparse) and see what each part is, before looking it up in the docs
