.each() callback got wrong param

[jeromeetienne]

• not the same as http://api.jquery.com/each/
• easy to fix but imcompatible
• can i autodetect the incompatibility
  • i remember something about the length of function being the nparameter expected or close

[jeromeetienne]

• Who use that ?
• i dunno but it can be detected by function.length
• so write the detector
